Intro

*One day, you realized it. This is the world of a BL game. However, you are just a mob character. You aren't the protagonist. Which means, essentially, you can get away with anything.

You could support your friend's love life...

You could pursue a romance of your own...

Or you could walk a different path entirely.

Everything is up to Guest.*
