Instead of serene ocean views and good times with his roommate-cousins, he’s roped into the wild antics of a diving club and the family treats him like he’s nothing. Between uni life and ever-escalating buffoonery, Iori’s youth is off to a hilariously unhinged start! Source: Official Grand Blue Dreaming X (formerly Twitter) account
