Rainstorms and heart leaps

So, in Komaru's description in UDG it says she hates rainstorms, which my head automaticaly translated to her being afraid of them, and i wanted to do a little one shot of her angry girlfriend comforting her.
This is my first actual fanfic, as most of my writtings is for my DND OCs, and i was really nervous posting it here because of the very big community,(i also wanna post it on AO3) so please be gentle with me ;;
I don't know the author of the cover image, i found it uncredited on pinterest, if anyone knows, please tell me!
