when oikawa was in brazil, he learned abt the tradition of giving the first slice of cake to the person you love the most. now i'm thinking abt ex-bf!oikawa who returns home, is celebrating his birthday, and he invites you. you're hesitant to go but you two split on fairly good terms, so you do attend. no one else in the room, you included, knows the significance of his insistence that you take the first slice of his birthday cake.
