He was insecure about his freckles. But you found them quite cute.

You would often poke his cheeks, specifically his freckles. Your finger would sink into his soft cheeks and bounce back. Sometimes, is you were in a good mood, you would kiss every one of his freckles.

He would also leave little kisses on your cheeks. But usually he was too nervous to and just ends up hugging you, which you also adored.
