#she just watches with that all knowing mom smirk yk… like she knows it’ll happen. katsuki is stubborn but he’s not dumb

[yuwuta]

f2l with katsuki but there’s nobody who rides harder for you two being a couple than izuku and not even in a weird pining threeway kind of way. just genuinely, from the bottom of his heart, he’s always believed you two should be together. he’s always watched you two growing up, he’s always chased after you two, he’s always seen the way you both lean into each other and still find space to pull him up too. he thinks you and katsuki deserve each other, he knows you two are meant for each other. it’s excruciating for izuku to watch you two not realize it for so long, heartbreaking to watch kacchan figure it out but not say anything, and the worst pain of all is watching you date other people because you’re too stubborn to realize your soulmate is has been right next to you your entire life. it’s exhausting, and izuku is bitter about it.

and petty. whenever you mention you have a date, his response is always “is it with kacchan?” “huh? no, it’s—” “that’s too bad then.” he pretends not to remember any of your boyfriends’ names and somewhere along the way he just stops pretending and really doesn’t care to learn them. he’s sweet and all smiles with everyone else, but the second someone other than katsuki is interested in you, there’s a straight frown on his lips. he’s out for drinks with katsuki and he’s noticed some guys eyeing him from across the restaurant, so izuku goes to greet them while katsuki is in the bathroom, all bright smiles and hero facade beaming as he signs the shorter one’s baseball cap with a sigh, “kacchan is handsome, right? you should see his girl, she’s stunning too,” capping the sharpie and any potential plans for flirting for the evening. he’s spent many nights gossiping with mitsuki and inko about you two, crying about how seeing you two dating other people is harder than any other mission he’s ever been sent on.

sometimes izuku just wants to shove the two of you in a locker and keep you in there until you decide to be together. he spends so much time with his chin in his palm, sighing with such yearning for a relationship that isn’t even his own. his eyes are soft right now, watching you and katsuki in the communal kitchen of the agency. there’s a slight glare shining through the glass walls, but he can see your smiles bright as day. you lean with your back to the counter, stirring your tea mindlessly as katsuki faces you, arms crossed but posture relaxed, no doubt saying something to rile you up judging by the slick grin on his face. you’re much shorter than him, but izuku remembers the days when you were taller than both of them back in second grade; he thinks the height difference panned out nicely. kacchan could lean down and kiss you right now, izuku wishes he would. a soft smile paints izuku’s face—they only keep that tea in the cabinets for the days you decide to visit, and katsuki only teases to hear your sharp tongue counter him. he must be in a particularly good mood today—or maybe, he’s happy because you’ve visited—judging by the way he throws his head back with a hearty cackle after you’ve said something to him. that’s good, hopefully you’ll keep his spirits up when they leave for patrol later. izuku gets so caught up in his daydreaming that he’s startled when there’s a knocking on the glass, and now you’re next to it smiling at his startled face and waving to him. he looks at you, then back to katsuki, who’s shadowed you to the glass wall, hovering protectively like he always has. izuku shakes his head in disbelief, but waves back. he finds the glass fitting, a window he’s looking into. he just hopes the scene changes to something more romantic sooner rather than later.
