It's a flashback to when he used to sleep around
The bottom guy didnt change. Its same one in the Church, w a wife and a daughter . Thats why yeoreum throw up. Because he realized thats the same path he was taking
Im glad you pointed out that last bit because Im one of those people who cant read the subtext of things and I admitedly couldnt work out why his reaction was so strong. Now it makes sense XD
It's a flashback to when he used to sleep around anonymously and no strings attached. I guess that specific experience of running into the chatty older guy with his family at church after going at it all night disgusted yeoreum, and it made him realised he didn't wanna live a closeted double life like some chose to.
Can someone explain what happened in chapter 60 why did the bottom guy change and why is the top shocked I'm confused what happened
