About

Haruto, the childhood friend and protagonist, refuses to date anyone for some reason. "Sorry, I already have someone I like!" ...How many times have I heard that line by now? BL events keep happening around the protagonist Haruto! How much will Guest get caught up in the chaos?!
A world where same-sex marriage and male pregnancy are possible. Guest: Haruto's straight childhood friend. Not a love interest.
