I’m Not The Popular Type, But 2 Girls Started Fighting Over Me - Part 1

Rena Aoi and Rena Kuroi. Miraculous collaboration between two people who should be incompatible with each other! I am a virgin because I am not popular enough, but for some reason, only my two younger sisters like me. One is the energetic and adorable Aoirena and the other is the slightly cool Kurorena. Should I have lovey-dovey H with Rena Aoi or should I try to force my hand with Rena Kuroi? I can't choose.
