There are two others but Gu man (author of love o2o) but they aren’t quite as cutesy and bubbly but still really good:
Boss & Me
My sunshine
Others than have somewhat the same happy feeling:
Queen In Hyun’s Man (Korean, but there’s a C-drama version Love across a millennium - also starring Zheng Shuang)
Smiling Pasta (Taiwanese and a bit old, cutesy relationship)
