I want the male to have one-sided love for female but ofc they should end up together. At first (not for a short time but for a long time) she will see him as brother or best friend while he actually loves her but can't tell her. But then she will start to like him slowly. Also, he should never look at other females. He should only see her.  Plase recommend me anything! My english is not good so sorry for mistakes.

Begin Again

Doesn't female fall in love first with him in that drama? I wanted male to fall in love first while female sees him as friend. But thanks anyway.

Try the Chinese drama Sweet First Love.  I also agree with the suggestion for Begin Again--the female lead does not love the male lead (in a romantic way) first.  She loves him as a brother, as they were raised together ,but it is the male lead who loves her (romantically) first.

I haven't watched this is a while but I Need Romance 3 might fit what you are looking for.

and when he says it... was priceless, one of best/emotional confession <3


also same is Reply 1988, but 88 is much better drama, really must see


I Hear Your Voice great drama, it's noona romance, she looks at him as young brother but he loved her for 10-12 years, and he looks at her so emotionally, all love is on his face (but when she doesn't sees, mostly he acts very confident and mature and is quite manly though he is very young) + FL is very good, strong and not so nice (in most dramas FL is annoyngly nice and kind)

I recommend Something In the Rain a pour love story with the same topic you asked.

It is very melo with beautiful relaxing OSD and environment.

i dont love you yet , this might fit your criteria . it is a Japanese adaptation of the very popular Taiwanese drama in time with you . many countries have also adapted it but i personally liked the Japanese one most

C-Drama "Go Ahead"  - has exactly what you're looking for, great show with lots of chemistry between leads and whole cast!
