Sanemi loves dogs but giyu doesnt as he got bitten by one once he was a child so giyu doesnt want any dogs
Giyu doesnt really have a sweet tooth but Sanemi does
As Sanemi is a foot taller then Giyu, he likes pissing off Giyu when he steals something from Giyu like, his book, phone etc.
Both of them are like parents to Zenitsu as Giyu hangs out with Zenitsu quite often and sometimes Sanemi joins in the conversation
Giyu doesnt like drinking really so the couple dont really go to clubs or any partys who feature drinking
As Giyu doesnt talk much, Sanemi, he mostly tries forcing Giyu to go lunch with his friends and that he should talk how life is going for the both of them
If Sanemi does something Giyu doesnt like (ex: taking his book away and forcing giyu to get it)... he will either not make ohagi or either force Sanemi to sleep on the couch 💪
When they have a kind of festival in Japan, they both like going to those festival as a date or its just to see the fireworks OR..... the food or games 💪
When they first meet, Giyu immediately fell in love w Sanemi meanwhile Sanemi had feelings for him later in time
If Sanemi doesnt come home from work, Giyu will call Sanemi if hes cheating on him but usually its bc of traffic or its bc he needs to finish shit before
Giyu is rlly clingy to Sanemi so everytime they sleep/watch a movie, he cuddles up to Sanemis arm
Sanemi makes simmered salmon daikon for Giyu almost every day for supper but instead they started making sushi and instead not eat the same thing
Giyu hates when Shinobu says that his husband is an asshole so he usually defends his husband bc he loves him more than his own sister
(SMUT IS NEXT OMGOMG)
