warning(s): established relationship, reader is best friends with rin, the itoshi brothers have a better relation
a/n: this the continuation of my best friend's brother two-shot but could be read as standalone, sorry this was kinda all over the place
itoshi sae who used to be jealous of rin at first because rin got to hang out with you and he didn't
itoshi sae who was an absolute gentleman on your first date
itoshi sae who asked rin for advice (albeit reluctantly) because he wanted this to be a day the both of you remember for the rest of your lives
itoshi sae who gave you your favorite flowers; took you to your favorite restaurant; did everything rin told him to do; even put in a lot of effort in dressing up because he wanted to look good for you - a complete gentleman
itoshi sae who's still a gentleman, of course. always makes sure to treat you right, spoils you to no end, tries his best to manage both his private and professional life
itoshi sae who's love languages are acts of service and quality time
itoshi sae who was a little awkward at the start of your relationship
itoshi sae who isn't used to being affectionate, but got used to it overtime and actually loves it
itoshi sae who doesn't initiates physical contact much butttt absolutely loves being babied by you
itoshi sae who doesn't have many nicknames for you, sticks to the basic ones, or just calls you by your name, but loves when you use a pet name to call him
itoshi sae who acts annoyed when you call him a stupid pet name but smiles afterwards nonetheless (please use stupid pet names for him in private only)
itoshi sae who you once called "honey munch" in front of his team and he blushed super hard, like full-on red (he likes to say he wasn't blushing but the blackmail photos from his teammates says otherwise)
itoshi sae who loves wearing matching sets with you, from small things like matching rings or watches to matching sweaters; absolutely anything
itoshi sae who acts extra affectionate towards you when around rin. and that pisses rin off to no extend, not because he's jealous or anything but because he knows sae is only doing it to piss him off and that pisses him off even more
itoshi sae who loves loves LOVESS sleeping on top of you; like, literally just plops down on you. girl/guy/chubby/skinny doesn't matter, he's gonna sleep on top of you when he's tired (only does it when he's tired and has absolutely no energy left because he's usually the bigger spoon)
itoshi sae who loves when you show him all the clothes you bought and pretend like you're a runway model and give him a little fashion show
itoshi sae who acts petty when you don't use his money to buy something like why are you using your own money when he has literally given you access to all his credit cards?? make it make sense
itoshi sae who once returned the item you bought just to buy it with his own money instead (yeah, he's petty)
itoshi sae who has your initials on his cleats because all his goals are made for you
itoshi sae who tries to learn your hobbies so you two can do things together
itoshi sae who puts efforts in "mundane" things because he doesn't want you to get bored of him and leave him (he actually enjoys it but he would rather die than admit it)
itoshi sae who doesn't want to live in a world without you. you're all he wants and he'll do anything to work things out between you two <3
