yeah...

This is deteriorating into something awful for Yeomin... Yeon is controlling him so much that his life is just school and hours and hours of forced sex. You know it's bad when Teomin's trying to do extra work for his friend just to get away from that situation for a moment. Does Yeon even like him, or does he really just like having a hole to fuck whenever he wants? He certainly doesn't seem to take into account Yeomin's pleasure in anything they do.
This is just waaaaay too one-sided of a "relationship" and it's so unbalanced that I'd almost say it's close to Yeomin being a slave at this point. He has no real say in what's happening, and every choice depends on Yeon's whims. Get this poor boy away from him.
