Even if Belphie tried to kill and did kill you once,you still love him and he loves you back.

You had your periods for about a day now,and it hurts. It hurts really bad to the point where you can't sleep or eat anything.

It was late at night and you couldn't sleep because your periods hurt really badly,you even started crying and had a mental breakdown in your room. And Belphie,the Avatar Of Sloth and the youngest brother of the seven sins,normally would always come to your room to cuddle and sleep with you. So he did come to your room and found you crying and having a mental breakdown because of your periods who hurt pretty pretty pretty badly to you.
