That time I figured out how to control the future

Rui is a loser, a virgin, and the oldest kid in high school, he's 35. Just when he thought this year would be another boring one, weird things started happening. His best friend was hit by a train while running along the track, his classmate suddenly became a lesbian and wanted to get married, and his literature teacher turned into a frog.

He thinks it’s all to do with fate, and he thinks he knows how to control it.

Will this help him finally graduate after repeating high school 16 times?
