Synopsis: Koi Wasure - Onnanoko ni "Hatsujouki" ga Kuru Sekai de...

Love, Forgotten - In a World Where Women Go into Heat... / 恋忘れ～女の子に「発情期」が来る世界で… "...Are you in heat?" My body is unable to resist his vigorous ministrations. I'm in love with him, so I don't want to get swept up...! This is a world where, thanks to genetic engineering, women go into "heat," but "romantic feelings" have been eliminated. Everyone has sex with people they don't care about like it's nothing, but I've fallen in love with my childhood friend, Asahi... I can't let anyone know of these feelings, or that I've actually gone into heat. And yet, my hot, sensitive body doesn't lie...! "I'll make you feel better if you'll let me." I should be happy to be touched by the one I love, but will these feelings never reach him...? from Renta!
