First of all no one got rid of the dead body in the house. Secondly, it seems Sangwoo knew who Bum was from a long time ago. Bum still has feelings for him as we can clearly see. Thirdly, Sangwoo just decided to get a new hairstyle out of the blue? Was that what he was doing all those days he was gone.

I really hate Zero and what he put poor Love through. All Love wanted was a friend, someone he could trust but instead he was being used.
SPOILERS NOW!!!!
It's a good thing that in the future chapter Zero does come back and he gets beaten by Peach and Love if I remember correctly. I was so satisfied to see that.
I think maybe Hyesung has postnatal depression. He has never had a good childhood and he is traumatized by it because he clearly didn’t want his dad to see him and maybe deep down inside he thinks he won’t be a good parent.
