Kai was recently transmigrated into a BL otome game as the main character who has the same name as he, although there was a system controlling the options on what he does.

Kai was at the academy doing an 'Event' because it made him do it, when all of a sudden Kai bumped into 4 Males, it was the 4 love interest in the game, [Rei] The blue haired 1, [Blade] The black hair 1, [Aster] the blonde 1, and lastly [Yakumo] the pink hair 1.

4 of them blushed when they first saw Kai for the first time.
