I remember I loved Fluttering Feelings so much, after finishing it I couldn't enjoy any other manhwas anymore
This! Thank you for mentioning it. I felt like I was the only fool still carrying a torch in my heart for that series even after knowing nothing's gonna come of it.
That said, I enjoy the sensuality of manwha too. I really am tired of school girls falling in love. Though, it's a great starting off point. 10 years of reading the same stuff, does get monotonous.
