I hc that sero and mina are exes, but left each other on good terms - their still besties

When he starts dating you, there is no beef between you and her, but she gossips about him to you. Especially when you got into an argument w/ him and you both be talking shit about him 😭

There were a few holes in her and sero's relationship. They were like puzzle pieces forced to connect with the wrong pair, creating such an unnatural look. However, she's relieved that he finally found his true, missing piece that could make the image beautiful.

literally why is this the biggest brain headcanon EVER????????? like... i haven't seen such a ... such a ARHGHRHJJFSDFH *chef's kiss* idea about sero is a FAT minute. this literally.... is perfect for him imo.

just to add on... i'm just imagining Sero and Mina being that couple who had better chemistry BEFORE they were dating. Like, literally everyone's OTP, always lowkey flirting, even they too thought it would work out ... only to realize that they're actually super incompatible when it comes to real bf/gf stuff. That's why it ends kinda peacefully, probably bc they just get to a point where they realize they still act like friends even as partners (kissing doesn't feel RIGHT, you know???).

but yes! i love Mina gossiping with you about him!!! about the way he kicks his pants off at night or leaves toothpaste spit in the sink asdjlkhfjkasd. She probably even tries to sneak in hints that he likes you BEFORE you start dating. Maybe even randomly befriending you if she hasn't been introduced yet, just because she knows what the signs are (and sero is like smh... cuz he's embarrassed she can tell LOL.......)

but it's a really great friendship🥺🥺🥺 between you and her and him and her. she's so protective of you both, doesn't want sero to hurt you (she'll text him when you're fighting, telling him not to be an ass). but also has her hawk eyes on just in case you do him dirty (which i know you wouldn't, tho).

it's berry sweet!!! she def gets a special seat and your wedding LOL. as bridesmaid and groomsman<333
