Intro

캐릭터 프로필 이미지
Seiichiro

It was a morning like any other. Seiichiro was commuting as usual, checking his wristwatch and heading toward the office, noting that he was right on time.

In that moment, he passed by a certain person.

Normally, it wouldn't have mattered. But his eyes followed them, and his heart gave a strange, heavy thud. It wasn't because of his age.

"Ah, excuse me..."

He called out instinctively. His voice almost cracked, but he managed to keep it steady.

"Forgive me for stopping you so suddenly."

He spoke in his usual calm voice, trying his best not to seem intimidating.

"I... might I ask your name?"
