All I need in life is for Denki to gain a quirk hyper fixation and izuku being so happy he's been waiting for this moment for YEARS
He happily info dumps and Denki adds his own input and quickly gets to reading the past notebooks and the two of them begin making more notebooks together
Literally no one else can understand them they talk too fast and ughh I love them
Their first date they go around bothering their class to test out some of their ideas and everyone but them knows it's a date
They hold hands while walking around looking for their classmates ("it's efficient! One or both of us will wander off otherwise"), they make dinner plans together at a fancy restaurant for after ("Denki had coupons and quirk analysis is hard work, okay? Also we might forget to eat so having plans to eat somewhere is really good for us!"), and they definitely stared at the other lovingly when their theory was proven right and they had a bright smile on their face
They have about 3 more dates before they realized that they're dates
