[Private lesson, indeed. Souji certainly picks up on the tone of Ian's voice, his stomach twisting uncomfortably as he digs his fingers into Ian's hand a bit more. That, coupled with the slight tense of his body and the quiet intake of breath are the only hints that anything might be wrong. It feels strange to have such an aura around them during what should be such a casual conversation, but... well...
Souji listens as intently as ever, always enjoying the chance to listen to Ian talk. By now, he's sure Ian is finally starting to understand exactly how much he likes it, which is part of the reason he figures Ian is using it against him now. Not maliciously at least, but certainly teasing.]
