There's a reflexive twitch in Togusa's hand, an urge to reach out for Koutarou's hand that he holds back at the last second. "I- didn't know."

Although, Koutarou's tone doesn't seem to have changed. Togusa ponders for a second before slowly speaking. "But..this isn't a big deal to you, then? Shuji was very worried about it, saw it as a potential vulnerability. If it doesn't worry you? Then I won't let it worry me. It was just very unexpected."
