Why We Did It Ending Explained: What Happened?

A month before Wendy Johnson and I are set to marry, she tells me she wants to have another man's baby. Following my refusal, she keeps bringing it up daily. Half a month till the wedding, I see her pregnancy report. Just like that, I find out she is almost a month pregnant. It turns out she has no intention of seeking my agreement on this matter. At that very moment, my love for her for so many years dissipates for good. I'm calling off the wedding and destroying all our shared memories. On the day we are supposed to get married, I join a sealed-off research lab without a second thought. From now on, Wendy and I no longer have anything to do with each other!

The night before my wedding, I was in a terrible car accident. I fell into a coma, and my body was broken and bruised. While I lay unconscious, my fiancé called off the engagement and married his childhood sweetheart instead. My mother went to demand justice on my behalf—but never made it back. She died in a sudden, brutal accident along the way. In that moment of chaos, it was my childhood friend who stepped in. He knelt on one knee outside the hospital with a wedding gift of a hundred thousand dollars and quietly handled my mother's funeral. I was wheeled into surgery. I lived, but was left with a permanent disability. And still, he promised to stay by my side, for life. I was deeply moved. We got married. But five years later, I overheard him talking to his secretary. "Mr. Davidson, you arranged for someone to hit your wife with a car, just so Lucy could marry the one she loved. Aren't you afraid she'll find out?" "For Lucy, there's nothing I wouldn't do. I've already given Ruby the rest of my life. Isn't that enough?" I covered my mouth, holding back a sob. Only then did I realize—the marriage I believed in had been a lie all along. So be it. I'll disappear and let him be with the woman he truly loves.

My best friend, Dominic Vale, and his girlfriend have created a couple's channel. Lately, their channel has gone viral on the Internet. I subscribe to their channel instantly. Every time they upload a new reel, I'll always watch it. But I keep having a feeling that Dominic's girlfriend, whose looks are censored in the videos, acts just like my wife, Cara Hartley. When I bring it up in front of Dominic, he punches me in the chest. "Oliver Beckett, you lovesick bastard! You see your darling wife in everyone! At this point, I'm going to get really jealous!" I just chuckle stupidly while rubbing my chest. Then, I quickly change the topic. When Cara's company goes on a field trip, I decide to drag Dominic along. Unexpectedly, something occurs during our flight back to the city. An air stewardess distributes notes to all the passengers so that we can write down our wills. With a trembling hand, I finish scribbling my note. When I glance at Dominic and Cara, I realize that they've written each other's names on their notes. Then, Cara turns on her camera, which shows both her and Dominic in the same frame. "Dominic, I'm very happy that I get to be with you during my final moments in life. Everyone, we won't be updating this channel anymore. Goodbye." But she fails to notice the way my face has gone pale outside the frame. Thankfully, the plane lands safely on the tarmac. All of us are still alive. Instead of kicking up a ruckus, I tear the note in my hands before opening the car door. "What are you still standing around for? Get in."

My best friend, Adeline Miller, and I marry into the Caldwell family together. Coincidentally, we become pregnant at the same time. I'm married to Rowan Caldwell, the older brother who's a famous psychiatrist. As for Adeline, she's married to Elliot Caldwell, the younger brother who's an extremely skilled doctor. Rowan gives me a ride to the hospital, hoping to accompany me to my prenatal check-up due to the discomfort I've been feeling throughout my pregnancy. But on the way there, he abandons me by the road and leaves me there because of a phone call from his first love, Veronica Whitmore. As I sob, I beg him, "Please, Rowan, I'm begging you! It's raining heavily right now! Can you please drive me to the hospital first?" Rowan shakes my hand off impatiently. "Veronica has slit her wrist! This means she might die! Can you be more understanding toward her situation, Emilia? I'm going to tend to her injury right now! You can go to the hospital on your own!" It's raining cats and dogs out in the world. Yet, Rowan doesn't hesitate to ditch me on the highway. Left without a choice, I can only call Adeline and ask her to drive over to pick me up. Unexpectedly, on the way to the hospital, we see a truck barreling toward us. While I'm unconscious, I hear Adeline crying while calling Elliot on the phone, only to get reprimanded by him. "Stop messing around, Adeline! Must you come up with all sorts of lies whenever I'm spending time with Veronica?" It's thanks to a passerby's help that an ambulance is called to the crash site. That's how we get to survive afterward. Alas, we both end up losing our babies. Upon regaining our consciousness, we just smile bitterly at each other. "Are you getting a divorce?" "Yeah."

My girlfriend, Clara Sutton, had severe mysophobia. Before every intimate moment we shared, she required me to disinfect myself thoroughly in advance. She even set strict rules about how often we could kiss or sleep together, and how long it could last. Without her permission, I was not allowed to touch her. I had always believed she treated everyone this way. I even secretly felt relieved, thinking that I must have been somewhat special to her. Then came that night at the bar. During a party, her childhood friend, Ethan Ford, drew a dare in a game of truth or dare. Then, in front of everyone, he leaned in and kissed Clara. Although it was supposedly a punishment for losing, they kissed deeply for a full five minutes. Our friends laughed and jostled one another as they turned to look at me. Only then did I realize that Clara’s obsession with cleanliness had never been a universal rule. It had existed simply because she did not like me. Disheartened, I asked for a breakup. But Clara soon regretted it. With reddened eyes, she begged me not to leave.

After her boyfriend bailed on their wedding, my best friend broke down crying and begged my fiance to step in and save the day. Blake Keller comforted me gently. "Dawn, Noelle and I grew up together. We've been close for years—closer than family, honestly. Today is just for show. Besides, our wedding's next week anyway, so think of it as a rehearsal in advance." I felt terrible for my best friend. After struggling with myself for a long time, I finally gritted my teeth and nodded. Just like that, I watched with my own eyes as my boyfriend, who was supposed to be the best man, became my best friend's "groom." At the wedding, Blake held Noelle's hand, his eyes filled with affection. When the officiant asked whether he was willing, he answered even more firmly than he had when he proposed to me. I kept telling myself not to take it seriously, that it was just an act and I should not overthink it. That was what I believed—until after they exchanged rings. The officiant smiled and said, "You may now kiss the bride." The crowd instantly started cheering, urging them to kiss. Blushing, Noelle hurriedly reassured me. "Dawn, don't worry. We'll fake it with the camera angle." I believed her. But in the very next second, Blake lifted her chin and deeply kissed her for real in front of everyone.
