It's really simple and straightforward, without any unrealistically convoluted story lines of revenge or dangerous people lurking around doing weird things. Also, there are no toxic story lines of backstabbing or blackmail or devious characters and there are no non-con elements either.

It's very, very normal really. Not much drama of any kind and the characters are ordinary, everyday sorts of people with normal feelings, which may not be everyone's cup of tea. If you like something with more action or drama, this will not satisfy you. The two ML's have over all good communication, there wasn't too much delay or hemming and hawing about their feelings and there were some valid reasons for their hesitations, like emotional, social and family considerations.
Aside from that it's very soft and fluffy and sweet, also very bright (I had to dim my screen in some scenes because of the lighting) and there are many softness effects.

I don't mind this kind of show at all, and I might have given it a 10, but I don't like the 'simp' vibe they gave Tae Sung, it annoyed me. I don't enjoy the 'give up one's whole life' for a lover/partner idea. It's too desperate for my tastes.
That's my only complaint.
