Story: The typical, over-used plot, where the main characters are in love with each other, yet because of the miscommunication they are not aware of the other's feelings so they will suffer in silence until a miracle happens, in our case the miracle was the third wheel who triggered jealousy, so the bear finally came out of the cave.
It was a bad attempt to show emotional world pain in a university setting with almost zero plot.
Also, what was this ”go away, but don't leave me” thing? They had to ”suffer” that much just to get together in 5 minutes.
Even though Daonuea was longing for years after Khabkluen's love, he didn't seem to be that happy and excited after they got together, in fact, he seemed low-key irritated when Khabkluen was trying to approach him.

Acting: The acting was pretty okay, with a decent amount of chemistry between the main couple. But I think that Joong wasn't professionally ready to be able to play someone who hides his love well.
They had their cute moments being together, but I got tired of it. Unfortunately, I couldn’t bring myself to like the main couple, nor the side characters.

Music: it wasn't really rememberable.

Overall: Nothing that really stands out about this series, nothing new and it could have had fewer episodes because what should have been an easygoing love story is strangely exhausting to watch.
But it's not that bad, I've seen worse, so watching this series is not a total waste of time, especially if you don't have that much expectations :)
