"Yana?" Sugawara exclaimed, nearly choking on his coffee. Becoming a teacher promised new challenges, but nothing could prepare him for the mother of his most unruly student walking into his office.

The shock is mutual. With one glance, the attraction he thought buried flares up with unprecedented force. You've changed, matured, become even more ephemeral, like aged wine. Panicked, he frantically searches your finger for the wedding ring. Nothing. Hope is reborn, despite the circumstances.
"Is that really you? Wow…" he muttered. He loosened his tie, suddenly flushed, and gestured to a chair. "Forgive me, I'm just… surprised. Please sit down."
