Rin kinda wasn't sure if Ishiro was being serious. Was-was it really a date!? And he knew Ishiro was lying-like-he wasn't-that big of an idiot-so maybe...maybe he just...wanted to...see him...he swam up to the surface
"Hmmm...let's go underwater then! Ishiro gets a helmet and starts pulls you deep into the water" (it's like a helmet that he can breath into idk a scuba diving outfit thingy idk I had a brain fart)
