Atsumu has been confirmed as the older twin, JSJSJSJA what kind of banter would ATCIT reader start when she (probably would) absent mindedly said 'i thought osamu-san was the older one'
Atsumu would go on some long-winded tirade about how he obviously shows off his merits as the clear and undeniable older twin while Osamu kinda just vegetates in the corner and (Y/n) nods along, listening until she says:
“So older in body, but not in soul.”
And Osamu loses his shit but gets right on it and uses that against Atsumu constantly who can’t do anything because you’re Madame Fortuna’s number one fan.
