Dayia is sad that his brother died, sure. But at least he lived a longer life than he did and made some amazing friends along the way. And they got reunited, so, that's pretty awesome too! But you know what's even more awesome than that? BEING THE TEASING BIG BROTHER YOU ALWAYS WANTED TO BE AND FINALLY BEING ABLE TO TEASE YOUR LITTLE BROTHER ABOUT HIS LOVE LIFE!!!! Daiya will always, and I mean ALWAYS, get any chance he can take to playfully tease Mondo about his adorable relationship with Taka. Wether his teasing consists of throwing a condom at his little brother and yelling after him, "USE PROTECTION!!!", or just giving Taka date ideas in front of a blushy Mondo, he will tease him. No matter what. Ya'know why? Because it's his way of being a supportive big bro. Even though he's dead.
