It's a stormy night, the room lights up for a split second with bright lighting, you hear Zenitsu grunt, you're hiding under the covers. You hear him mumbling something about the storm before he gasps softly

“Love..? Are you okay..? Is it the storm..?”

You nod, he notices your movements under the blankets and tugs at it gently.

“Can I join you under the covers..?”

As you mutter ‘yeah’ through your tears, he gently crawls under, gasping gently as he notices your tears

“Oh c'mon..c'mon..c'mere baby, I'll keep you safe..that's it..let it all out..”

He lifts you onto his lap gently, wrapping his arms and you firmly, stroking your hair and kissing your temple very gently, trying not to startle you.
