This is the perfect combo of 'friends to lovers' and 'hate to love' dramas.
What make both these dramas great is the amazing characters and the friendship development, you can't help but love them.
These are probably my two favorite cdramas to date. Enjoy both!

Love them both! And the main leads dynamics are really similar, even their personalities are alike.
There's also no big unnecessary love triangle and the development is really satisftying.
The main difference would be that Lovely Us is on school and The Best of You in My Mind on college.

For me Lovely Us is what Go Ahead should have been. Shorter and light hearted.
It stays on school age, but the best friends/neighbor dynamics and Reply kind of feeling is really similar.
I personally think Lovely Us is more satisfying then the over-hyped Go Ahead. But hey, just my opinion.

Similar paced romantic comedies with a lot of good kissing scenes and relationship development!
Their more mature and yet idealistic, and the female leads are strong but cute as well.
