Typical "can'te get out of room until H" between MC's brother who doesn't seem to be an asshole (still far from a bro) and MC's GF.

Btw, they were supposed to return as if nothing had happened (no memories and hymen) but something went wrong and the memories remained, they said maybe it was a bug or something (meh...). She said "sorry, Kouji, I might be still a virgin but I already have a baby with Masato in my heart"

Also, they are childhood friends and they started going out a month before that. The brother confesses to her in the middle of the story (something like "how can you be so calm in this situation?" "I'm ok with this because I always liked you".
They were inside for 2 weeks
