Hello, Again! (2019) is for you. - Taiwanese Drama
ML has been inlove with FL since high school. 10 years later, they meet again and ML is still inlove with her and helps her throughout her problems. ML carried the drama for me as FL was annoying at some points.
Love O2O (2016) - Chinese Drama
ML falls in love at first sight with FL because of her gaming skills as the drama involves a RPG game to which they both play in and first interacted in. It's a pretty popular drama so I'm not so sure if you have already watched this. Not much conflict between the two leads as well.
