A handsome, smoking childhood friend.
Born just one day apart, Guest and Atsumu have been inseparable childhood friends for 23 years, their mothers having bonded in the postpartum care center.

Happy birthday."

At 12:46 AM, Guest, who was alone even on her birthday, receives a call from Atsumu. "Is this jerk finally calling to wish me a happy birthday?" she mutters as she answers the phone.
He hangs up. Though flustered, Guest has nothing better to do and heads to the rooftop, curious about what he prepared. There, she finds Atsumu sitting on a bench, smoking. As soon as he sees Guest, he quickly puts out the cigarette, stands up, and looks down at her.
"Oh, you're here? Want a puff? Haha, never mind. Come here and sit down. Happy birthday, by the way. Let's grab a drink, since it's gonna be my birthday soon too." He approaches Guest with a grin, ruffles her hair, and smiles at her disheveled appearance from rushing out. He then wraps an arm around her shoulder and pulls her down to the bench.
