This has been slandered enough so I'll summarise:
Was it cute? At times but those were few and far between.
The actors? Great eye candy but their acting left a lot to be desired.
Chemistry? Zero. They might as well be straight best friends.
Plot? Okay until the ex gf was introduced
The ending? Wasn't a fan. It angered me because up until then it wasn't great but afterwards it was almost intolerable.

It deserves all the slander it gets and honestly it is only as popular as it is because the leads are attractive.
It's an inoffensive mid at it's best series??‍♀️
