Guide esper

Pls help me, I forgot the title

Mc (guide) died on a mission (I think because he sacrificed himself for his teammates, they were in the enemy base but turns out it's a trap). Then as he's dying, he got a flashback about ml (esper).

Mc was a rich kid and a S or A rank guide, so he kinda acted like a brat. He met ml at the academy and forced ml to be his partner while there's a rumor that ml already has a sweetheart (I think). At the end of the flashback mc regretted what was he doing and hope that of there's another chance, he wouldn't force ml.

Then yk, mc back to the past when he was a student and try to avoid ml. Mc has a blonde hair and ml has a black hair.
