FINAL CHAPTER: Yoosun delivers her newborn with Yunho and now they have two kids, so they can't do it as often. Yunho gets himself a corporate job, he there coincidently meets Bora who now lives in England, hey chit chat a bit and everyone goes their way.
Yunho came to Sunmi's house to inform her that he's quitting but she's already waiting for him in sexy lingerie ready for the fucking for one last time
Bora is annoyed that she keeps running into her ex-boyfriend and hates that she still misses him. So, she drags into a motel to fuck all day. Shagging was so good had her forgiving him mid sex. (Post-Breakup sex)
Sunmi guesses exactly the reason for Junho's outings and wants Yunho to rail her right infront of the camera Junho set up to give her son a good fap material.
Bora is extremely bitter and obsessed with the idea of breaking apart Yunho & Yoosun. So, she stalks Yunho throughout the whole summer. One day, the in-laws go on an outing together with Hayul too, she stalks them through the entire day. She feels that she wasted her time doing so as nothing suspicious happened during the whole day, but later at night her fears come true as she clearly sees Yunho and Yoosun fucking passionately. She interrupts them and gives them a good scolding & even threatens to snitch.
