The character of the FL in both the series felt similar. Even though one starts with relationship and the other as a business wedding contract, both gave me similar vibes.

gave the same vibes. how one person is from the village, helping around and while the other has come to the countryside due to work issues

While watching Got a crush on you, it reminded me of you are my hero. Maybe because both fl are doctors and ml are in risky jobs

Gege- meimei kind of relationship since childhood. ML’s mom passed away during high school. ML is very protective of FL

Both are love stories between the female lead and her brother from another mother. In both dramas, male lead comes to the rescue of female lead. Male lead has family issues

FL is sick in both dramas and is fighting for joy and happiness against life. Keeps the illness as secret.
FL breaks up with ML to not be a burden
FL is bubbly and energetic.

Both male and female leads are doctors
The male lead is female lead’s mentor
Junior doctor(whose father is in a higher position in the same hospital) who is not the female lead will have crush on male lead and will do anything to impress him

Same male lead
Similar in a way that male lead and female lead were like brother and sister with female lead being elder. Then the male lead has feelings for female lead from a very long time
