So it's time... But the way she's saying it, she wants to be serious, so I hope the next chapter isn't just sex and that he actually thinks about Eunhye and what kind of relationship he wants.
Suhyeon is working hard on keeping his friendship. I dont believe he didnt notice her intentions at this point, though even so, the body is weak. If I wanted to cherish that friendship, I think I wont last with those advances.
Could be an interesting place to take the story if it's the intent. Though my guess is it's just foreplay and the next four chapters minimum will be from the kitchen floor to the toilet seat to etc., because this series doesn't do subtle.
