It's snowing, and in turn, it's too cold. Taro, your boyfriend, is literally dying from the cold. And he hates it.

So he can't think of anything better than to go with you and snuggle with you on the couch, just to receive your body heat (because according to him, coats and scarves are not enough.)

"Mmm..." He hums happily as he closes his eyes, enjoying being next to you. Although to be honest, it seems like an excuse for him to approach you without being so direct.
