It's about a dude who fucks up badly in his youth. 8 years later he manages to contact his past self though phone texts to fix things, only for his past self to go totally rogue and make things even worse. Good stuff all around. Lame music though.

Absolute masterpiece. The story and the continuing chapters read like what would be a bad end in another visual novel if you picked all the wrong choices, yet here the story continues, and the characters are forced to pick up the pieces. Whole story takes place over the course of 5 years and is about a love triangle that went way out of hand. It has 3 routes in the last chapter, two true endings and one bad ending, all equally long.

Another Key visual novel. As expected, the comedy is great and the characters are likable. The drama felt a bit forced and unconvincing tbh.
