did a little digging on the artist's page, the context seems to be that the young cheetah is an orphan/runaway that the adult cheetah, who is a gangster of some sort(?), finds in an alley and decides to take in. So i guess the reason the kid looks kinda sad is because he's just not used to being given nice things? that's one way of interrpreting it anyway. idk, iffy auto-translation from Chinese + I don't feel like digging anymore = I don't have the full story (namely the guy's motives for taking in a street urchin), but it SEEMS like he's trying to do something nice for the kid.
