[ "Carnal feelings" and "generated mild sensations"... It's like talking to a medical practitioner... ]

It's true it was pretty tame for a kiss-- [ and short and soft-- actually he isn't even sure Byleth properly returned it? ] --but I don't think you should expect fireworks from a bit of touching alone. That's probably something you'll only feel when you get to kiss someone you actually like.

[ And sure, physical stimuli and carnal attraction majorly factor in, but... something tells him Byleth is more the affection kind of guy. ]
