this drama isn't masterpiece but it is one of the best in genre, I mean it has every element what normal mature romance story (or rom com) needs. I've seen many many dramas for now and I can say it's not usual 100 times seen romance/relationships, it's not usual clieches, it has slice of life vibe and real characters/relationships. Plus main characters and also side characters have real good chemistry and goo acting. also story isn't dragged, also romances and feelings aren't rushed (it's often when main characters are in love so suddenly you can't see why or from when, it's out of sky and viewer doesn't have enough time to feel it).

mature audience will more appreciate it, because every character and relationship is natural and realistic and with that they don't loose good chemistry and kind of fairy tale-ish charm (what's usual for dramas with more realistic relationships).
FL - mature woman who understands life and love, that love isn't fairy tale, she isn't usual 30+ never been kissed FL who is waiting for one true love. sometimes she is still naive but overall realistic character.
ML - as he is younger it's understandable that he is more romantic, perfectionist, believes true pure absolute love, tries to be 100% conscientious in love and relationships but can't always be like that because he is also human and man in love who is jealous.
SML - decent good guy, good friend and boss, man who was madly in love with other woman but it that relationship was too hard and painful, so now he wants simple safe mature relationships and it's very very normal, I can understand him, I have exactly same situation and desire. He always was honest with FL and SFL, so he really is good normal guy and very realistic character.
SFL - also good person, I mean real person, not too perfect or too bad (as it is usual in dramas). she is very proud and strong woman but is ready to step on self-esteem because of a man she loves so much, he is her only "weakness" and that is also so real life situation.

relationship between ML and FL - they really have chemistry, a sweet and also realistic chemistry, they have brother-sister kind of chemistry and also hot sexy vibe at times. we see how deep ML is in love, but feelings of FL isn't romantic love, and it's normal, it's understable, she was like older sister, even like mother to this boy, she doesn't sees him as man, on the other hand she has someone else quite nice man (not boy), who thought her many things, was always good and nice, real friend to her. and the fact that he loves someone else doesn't make him bad, he is honest every time.
overall I think main couple had friendly like family member chemistry and at some point I thought it would be better if they won't end up together, but drama could develop this relationship also very realistically, we see how and why started FL see him as man, at first she was just used to be around him every time, plus he is so comfortable and lovely roommate, then she starts to compare her dry mature relationships (which aren't bad when you are mature, I can see, but in every woman is inner self who wants crazy emotional love) to that one ML could offer. if there wasn't ML with his soo big love to her, she would be satisfied and happy in that relationship. I like when drama shows it - in real life love isn't one and only, when you can't be with anyone except that one.

I like that in this drama love triangle isn't usual and it's also refreshing, not one more "2 guys crazy in love 1 girl and she loves ML but triangle is still dragged", it was good to see that SML is the one whos in center of love triangle and not in love with FL.
as I mentioned main leads have real


so really recommend for them who wants so see mature, real life love stories, realistic characters and relationships, without too perfect main leads and forced "bad" second leads or villains.
