Before she can answer, V arrives. The MC takes this opportunity to try and escape by distracting the security guards, but Jumin quickly intervenes, and she is caught. Jumin does not understand why the MC is trying to run away, and V says plainly that it is because Jumin won't let her go home, and also mentions Seven's concerns that Jumin has been overly possessive. Jumin does not understand why the MC has an issue with him. While V and Jumin argue, the MC opens a window in Jumin's penthouse, and tries to escape.

V appears and Jumin stands before all the other members, his father, Glam, Sarah and the reporters and begins his speech; he tells the audience how he was once an unfeeling man who never felt love, but it all changed when he met a certain woman. Glam, his father and Sarah all mistakenly believe that the woman Jumin speaks about is Sarah and Sarah prepares herself to step up on stage before Jumin announces that the woman who has changed him, and the woman he loves, is none other than the MC.
Jumin reveals all that Jaehee and 707 have collected to the reporters, effectively ending Glam Choi's hold over the media and exposing her and Sarah's secret: that Sarah is actually Glam's sister and Glam forced her to get a new ID and get plastic surgery after the failure of her company, Sugar Round, in order to court and marry Jumin while Glam would marry Chairman Han. Both Sarah and Glam are shocked and unable to defend themselves as Chairman Han orders Glam to say that it's all a lie - which she cannot say, asking if this end in a lawsuit. Sarah attempts to regain control again and gets up stage in order to confront Jumin over the evidence, saying she gave him everything, while Jumin says how can she give him everything when he doesn't even have her phone number?The reporters rave over the news and Jumin pushes through the crowd to the MC, much to Jaehee's worry over him doing something wreckless. V reassures her that he won't - instead, he's going to do something romantic. Jumin meets the MC halfway, telling her how beautiful she looks and that he loves her with all his heart. Jumin then proposes to the MC in front of all the reporters and other members, confessing his love and thanking the MC for being there for him every step of the way.
It is revealed that the player and Jumin had gotten married shortly after the events of the Good Ending. The RFA members discuss about the prospects about their relationship, before going to the airport to welcome them back from their honeymoon. As both are swamped by reporters, Jumin requests the player to 'put [herself] above everyone's eyes... and put [him] in second place' as he wishes for her to choose 'a selfish life where [she] puts [herself] above everything else.' The ending concludes with Jumin answering the reporters about how he truly loves his wife.
