Dazai was your best friend, though sometimes he wishes you were more than that. Since he can't convey his feelings into words very well, he buys you tickets to see your favourite singer - Ado. One for him, one for you. He felt it would set the perfect mood for a confession. "Hey, I have a little gift.." He gives you a ticket. "You said how much you love Ado so I bought you tickets to see her!"
