is it possible to gain muscle while being very lean?

i was just adjusting my goals for gym. i got to the point of having ab veins and along my hip area too (i have average vascularity genetics i think just fyi).

the aesthetics are nice, like the classic anime physique goal, i developed decent amount of muscles in 2 yrs.

thought about stopping the cut and maingain from where i am now but im unsure if its possible to grow muscles being this lean. before gym i was skinny fat but mostly skinny, so maybe being slim by nature might help?

my energy is really high, i feel more athletic and happy overall which I didn't expect.
