OHHHH this is an interesting one....

i would say that it honestly has a lot of different ways it could go, to some degree i feel like with how much time they spend together it's hard to figure out when their First date was as a lot of their hanging out could inherently be dates in themselves without them realising. i kinda just imagine it like theyre both inexperienced w dates so they just settle on each of them dragging each other around random places but specifically like a fun one i always think abt would be an arcade date like midori runs straight to the plushie claw machines (they are both awful at them) (tetora tries to look cool) (tetora uses all his money for a plushie for midori) and tetora pulls them towards one of those boxing machines LMAOOOF and they make a tournament with all the arcade games (loser buys buns on the way home) (midori loses) but like overall i think they would just be having fun like normal then it sets in like Wow i am on a date... they both feel like the type to get flustered easily by the thought tbh... maybe afterwards they walk home n get distracted by the pretty stars... i bet tetora says smth corny n midori walks away LOL... i mostly just see it like their normal everyday but with the sudden new consciousness that they're actually dating. nothing too serious yet cause they are too shy. my favourite losers they r in love
