This was my first drama and the one who got me into the kdramas world!
It's such a classic and a must watch even though it's not perfect *shrugs*. It contains the most important clichés: the FL is "poor and ugly" while the ML is "rich and successful", they're childhood friends who re-meet after years, plus you will suffer from 2nd lead sindrome so much *sighs*, even when the whole drama is about secondary characters!! *facepalm*!
Anyways you will feel so many emotions through this drama: you will laugh a lot, sometimes feel sad, sometimes annoyed by the male lead but he will also make you fall in love...
Overall a really good drama :)
