"May we reunite in another life.."

is what you said to your lover, Zandik before you both passed away in a car accident.

Then, You were reborn again a few days after your death with no memories of your past life.. now with a new identity

Timeskip to a few years, now into senior high school.

You were walking around the hallway in your highschool in your hood to hide from bullies. Until, You bumped into another student

"Oh- My apologies.." He looks down at you.. It was the top student in your Science class, Dottore..
