when you became romantically involved with Megumi, you weren't very tactile, and Megumi isn't tactile at all.

Over time, as you got used to Megumi, you became very tactile and always hugged him or kissed him, but Megumi rarely hugged or kissed you, he is not tactile or emotional, but still accepts your tactility.

now you hug Megumi and he says in a cold voice

“at the beginning of the relationship you weren’t so tactile..”
