When Wakasa asks if something good happened, Tatsumi shyly admits his manager gave him a raise and allows Wakasa to splurge a little. Wakasa grins at Tatsumi's offer to splurge, and Tatsumi buys Wakasa a massive amount of milk. While Wakasa enjoys his milk bath, Mikuni, Maki, and Takasu arrive...

Ça réchauffe jusqu’aux os.
Você é leniente até o último fio.
