(straight people...
you can have two girls or two guys spending all their time together, making each other blush and happy, thinking of each other all the time, saying they're each other most important person in their life, going to the end of the universe and beyond and even through literal hell for each other... and they would be "oh they're just girls being cute friends/bros being bros
but then they see a man and a woman gasp- talk to each other once in a while and they would ask "when are they getting marriieeeed?! you don't understand they both love cats, so they must be soulmates!!"
honestly hope the author will keep this manga romanceless, and again I really don't say this often, but here just no, i'm tired)
