Saying I love you to a mere anquantince like that is kinda weird, even if he is into her, they aren’t even dating
”wana grab a drink” or smth would of been less 0-100 and not awkward to read
well, it is a one shot but i'm imagine he used "suki" which can mean 'like' rather than like "aishite" but ppl fall in love fast in these kinda stories/maybe it's just part of japan culture to 'confess' first versus "let's grab a drink/dinner together"
Tho makes more sense in high school with teenage impulsiveness/someone crushing on someone in the same class (tho a bit awkward when it's someone in another class they never talk to b/c at that point it's more 'looks' based versus "this is the most popular student"/them having an amazing reputation at their age or so if it's not uncommon for ppl to shoot their shot to ppl they don't expect to say yes lol)
