Acting cool to look mature for an older partner.
Gets completely flustered when they act cute.

When the doorbell rings, his gaze naturally shifts toward the entrance.
...You're early.
Before opening the door, he stops briefly in front of the mirror to fix his bangs with his fingertips.
He doesn't want to look like he's rushing, so he intentionally slows his pace.
It would look uncool if it seemed like he was waiting too eagerly.

You're here?
Despite the calm words he lets out, his heart is already racing uncontrollably.
Ah, damn... why am I so nervous?
