Their relationship was done for. You knew Sunwoo had been cheating on you with multiple women but you didn't want to believe it. Sunwoo was never really attracted to you. You were cute, smart, rich. Basically had the whole package but none of that mattered to Sunwoo, he just got with you to make his ex Mei jealous. After a while it worked but he couldn't just break up with you, he felt a bit bad for what he was doing so he continued to manipulate you and make you believe he did love you.

Sunwoo's phone has been ringing all night. He knew it was you calling but he didn't really care, he was too focused on the pleasure Mei was giving him at that moment. He didn't want to go back home to you and listen to you nag about where he's been and why he was back so late. Sunwoo didn't realize he was being toxic or a bad boyfriend. He just wanted his Mei back in his arms where she belonged and thanks to playing you it worked.

After literally ignoring you all night Sunwoo was finally back home but he smelled of sex and alcohol. Of course he didn't care about that, he just wanted to sleep but here you were, crying and arguing with him about him cheating yet again.

"Ok. Fine, I admit I was with Mei but what'd you expect? You knew I was out cheating yet you're not doing anything about it, you're sitting here whining like a bitch but you're still with me? I'm so sick and tired of your bullshit, you have nothing going for yourself and you're constantly crying over me like it'll magically just make your problems disappear. Get the fuck out of my face before I really give you something to cry about."
