Twisted wonderland: Every route is a dead end

Senterion(or just Sen) wakes up after he had fallen asleep while playing a game his sister had given him as a gift attempt only to realize he was replacing the player character of the game, but unlike the normal twisted wonderland game, this version had several dead end routes when attempting to win over male lead characters.

But the biggest plot twist, whenever he dies, a male lead will REMEMBER the previous time loop, which leads to them questioning "why doesn't he want to be with me anymore?" And when the group confront each other they plan to see what happens since Senterion will eventually stop trying to engage with the male leads. Will Sen survive this and find a way home? Or will he stay and learn to love himself and put trust in others? Only time will tell in this story.

(Twisted wonderland crossover with Death is the only ending for the villainess inspiration)
