Why Did the Heroines Turn Dark After I Rejected Their Confessions?

[Multiple Heroines] [Mild Yandere] [Goblin's Ultimate Fantasy]

The heroines, who love you more than anything, confessed to you, an ordinary passerby. When you rejected them, they all went dark and turned into yanderes.

I, Chen Mu, was just an ordinary college student. But after dying from playing too much Galgame, I ended up in the world of a text-based game. All I wanted was to lie low, pass the time, and finish the quests.

But why are all the yandere heroines confessing to me?!

Underclassman: "Senbai, don't go wandering off, okay~"

Campus belle: "Darling, you know I'm only in love with you. Don't make me tie you up, okay~"

But I'm just some random passerby!
