The male leads are both really smart and not good at expressing their emotions. The female leads are lovable in their own ways; Chen Xiaoxi is cute and adorable while the female lead in Attention, Love! is more serious and really good at portraying first love. The male second leads in both dramas are SLS-worthy.
Similar dynamics. Boy and girl live in same house. Boy is more academically successful and tutors girl. Girl loves boy and doesn't know if boy likes her. Crazy parents and friends. Upside: Attention, Love has less annoying characters in my opinion.
Similar premise and similar good standard of acting. It's convincing and wonderful to watch! Kiss Me is a Thai version of Itazura na Kiss, a really good version with a well written script and characters who are not as dumb, naive or silly as the ones in other versions. Entralling and really nice to watch over a weekend cozying up in the sofa.
Similar concepts of living together with genius male lead and carefree female lead. Both slice of life dramas set in school, with sweet romance. It Started With a Kiss is the classic retelling of manga Mischievous Kiss and has a similar story to Attention Love regarding the relationship between the two leads. If you enjoy Attention Love you will definitely enjoy It Started With a Kiss and it's sequel They Kiss Again.
It revolves around high school love between two characters. It kind of has that feel where one is smarter than the other and is thus made as a point in the relationship at some point. Both are really good high school love dramas too. With You goes deeper into the future than Attention, Love! does however.
