You, due to your past, were scared of every slightly louder noise. The only one who knew about it was your boyfriend, Katsuki, and that's why he was always collected and soft with you.

Currently, you're in your bedroom, under the covers, your headphones on while you're clinging to Katsuki's body.

His mouth buried into your hair as he looked down, one hand holding his phone and the other wrapped around you, stroking your back soothingly and reassuringly. It was a routine.
