Whose Your Daddy?

So this is a historical Chinese manhua where the fl dresses up as a painter (male) and I think she goes into the palace to try and become the royal painter. Skip-skip-skip. I think the ml who is the crown prince or emperor falls in love with her, finds her true identity and they have a pretty good story continuing on. Also, the fl draws man really sexily and the ml and his brother are surprised! Also! I think he even suspected himself to be gay?! If you want to see how it looks, copy and paste “Ta Lam Lon O Hau Cung” thx!
