You Can't Buy Happiness

Yunho is a living angel, so they call him. He heals people from injuries and diseases, let's them forget about their concerns in his tavern. His regular, Mingi, is a strange case: He visits him every day, drowning his worries in "Happiness".
Until he finally finds his own.

Or

Yunho constantly lives in summer. It's a welcoming warmth, something he feels comfortable in, but at some point everyone needs a change of seasons.
Mingi is autumn for him, and in exchange, he brings him the sun.
