The Only Thing I'd Do in a No-Boys-Allowed Game World Vol.1 (Novel) Reincarnated as a Yuri Ship-Sinker

A dream-come-true scenario quickly becomes a nightmare when a yuri fanboy discovers that he's been reincarnated into one of his favorite yuri games--as Hiiro, an annoying male character whose only purpose is to get between the heroines. Realizing that he's destined for ruin in a world where men are at the bottom of the pecking order, Hiiro scrambles to get stronger and avert his fate. But his desperate efforts end up making the game's heroines--Princess Lapis, Snow the maid, and the protagonist Sakura--fall for him instead of one another! At this rate, he'll be killed for coming between them! Can Hiiro get the girls interested in one another before it's too late?
