If you are interested in a manga that is kind of similar (gimmicky, plot-heavy), but with a better story, you might want to check out Isekai NTR: Sullying My Best Friend’s Women with the Strongest Skill. I never thought I would be rooting for the MC to seduce his best friend’s crush before, but the first major arc in this story actually tells a pretty compelling story and gets you to cheer for it as well. I swear that the MC is a good guy (-ish) despite the titular NTR.
