It's not the end, don't worry, there's a lot more
Noooo! They are finally happy! If there is a lot more, there will be sadness and crying and drama and--- I refuse. It ends here. Happily ever after!
No. I meant the older guy Han Jung Won. Did Min ever have sex with him? But thanks for the answer that was gonna be my next question. Please and thank you!
The night he thought he had been dumped by Chun Sam, he got drunk, and while passed out Han Jung Won came onto him. They never show the actual scene, but we do see a flashback later of Min showerng. And he does tell Chun Sam the next time they talked that it was too late, that he had slept with someone (he's so pure to think that sleeping with someone means you have to go out with them ha ha)
I can't be 100% sure, but I think we see their first time in the next two chapters. It's pretty plot heavy, so it's understandable why it was left out. It's also pretty dark.
I can't seem to remember when was the first time they did* it...and I don't know but that felt like the end. :/ wtf I didnt quite like the fact that he was drunk to do it...like I know what it feels and it's not like that all cute and stuff most of the time you feel dizzy :/
