Hello!

First time on this website and was hoping i could find an answer here. A few years ago i read a manga or maybe it was a manhwa about a boy who made a deal with an older man to date his daughter. She is blonde. She is cold to him but makes him take her shopping. Her circle of friends are jerks and they usually hangout in hotel rooms and seem to openly fool around with each other alot. The boy ends up spending more time with her...they fight often and eventually he finds out she has deeper problems underneath. i think she is depressed. They do make love as well. These are the only memories i have of it since it was so long ago.

Does it ring any bells?

Sounds like it might be Velvet Kiss.
