One Inch of Yearning (2020)

In both dramas the male lead feels betrayed by his father or father like figure. They both travel around alot and also help the ones that the rest of the world thinks are bad but are actually good. Bothe male leads fall in love but don't want to admit it.

Both dramas have a ML who is sickly, weak but highly intelligent and masterminds of everything, at the same time somewhat charismatic. Both FL are good at fighting and becomes intangle with ML due to some past who needs to be investigated. Both have similar humour and quirks, but The Moon Brightens for You is more comedy than Love in Between.
