One of the best cdrama I have watched so far can't understand why people are disliking it on the basis of age gap like seriously it is not like they 10 or 12 years of age gap , it's just 5 years and we can clearly see that at the age of 14 she only had a crush on him when she was at her adolescence, any girls at her adolescence can have a crush it's not new and the ML started to like her back when she was an adult not when she was a child . And for those who were saying that ML was getting closer to her , so it's basically she treated ML as a family and he felt warm which he hasn't felt before which was depicted in the drama about his past , so it was natural for him to get closer to FL .
