it's still registering to tadashi that his best friend has a crush on his sister. though, he's not surprised. it was bound to happen anyway. tadashi knew that you, his sister, and his bestfriend did not play around when it came to relationships.
so, it was funny knowing that his best friend could end up being his brother in law. having known each other since junior high, it was only natural kei got close to you like he did with tadashi.
he came over to you and tadashi's house and you'd occasionally went over to his with your brother sometimes. you all walked to school together as a trio. a little thing that began in junior high followed into high school.
kei's crush on you followed, too. he would've thought you had that figured out right now, but you were just too clueless in your own world. he wanted to be part of that world; your world. he wants you in general. to be with you.
"i'm not sure if she's home from her club yet," tadashi says to kei as they step into the house through the front door. both of them find their eyes on you in the kitchen. "oh, you are home." tadashi smiles and walks up to you, greeting you with a side hug like he does all the time.
