Overview
"I'm going to be in a relationship with my step-sister!" Wait, who decided that?! There was no way he was going to fall in love. Since that traumatic event from 2 years ago, he avoids love like the plague--When his dad gets remarried! Now he has 2 sisters?! This must be some joke!! Even though Aoba wants nothing to do with the sisters, they always find themselves in sticky situations. Can they open his "door" to love? The beginning of a juicy story bound to make life a home a very ending love battle!" (Source: Coolmic)
