MTL - A Smile from the Villain - ~ 30 tangled

When I opened my eyes, I found my soul synced into the popular dating sim game, ‘Midnight’! And although I was clearly one of the female protagonists, I possessed the body of Evenes Harin, the saint who is treated like a trivial extra. What’s worse is that I must pursue one of the five male love interests and see it through to a happy ending in order to complete the game.

Having attended the triple combo of an all-girls middle school, high school, and university wasn’t enough of a debuff, having unintentionally put up an iron defense, I’ve been in ‘forever alone’ mode for 25 years. On top of that, I’ve possessed the Saint seldom played due to her atrociously difficult route! This life is screwed up, and I’m sure of it.
