SDAB-253 "Should I let you graduate from virginity?" My caring playhood friend gen

My childhood friend Uta is a caring girl who always takes care of me. When he found out that I was a [virgin], I was worried that he would be my first partner...! After that, every time I met him in the library, club room, classroom, etc., he started asking for me and fell in love. However, as if betraying me, I started having sex with my senior's handsome boyfriend in front of me...
