this drama isn't something you haven't seen or mind blowing story, but one of most pleasant drama to watch. it is fresh, funny, healthy and realistic relationships, no cliche and taboo, gives you positive feelings and makes you smile.

there are little things, that is really unic and different, not usual in 90% of dramas. for example: ML is positive funny guy who isn't "wanna be bad boy" or "wanna be most cool guy", not CEO, not rude, not crazy jealous masculine and not all that architypes we are used to in dramas; he is ordinary (but not ordinary) nice guy, very communicable, in good relationship with everyone, not most popular but not last one, jokes, drinks, goes out with friends (he has many friends), likes women (not sees only one girl the whole drama as MLs do usually) goes on dates and looks at life with smile. nothing special right? but he is so light and realistic, and so not like 99% MLs.
Also there is real friendships between girls and boys, even with them who then fall for each other, quite long time there is pure real friendship without hidden feelings and all the same plots and scenes we have seen 1000 times and these little usual things make this drama real fresh and realistic and interesting.

I've watched it some time ago but still missing the aura/vibe/atmosphere of it. in some dramas this atmosphere is done soo good they make you feel it strongly and even after some time, even if you don't remember full story you remember that atmosphere and miss it (for example reply 1988 had is strongly)
