Siwoo and Hakyung
- they met arguing
- they quickly dated
- stagnant (they kept it secret so there's not much interesting happened during their relationship, its just a secret)
- they broke up (si-woo, doesnt want marriage, he doesn't want to burden Ha kyung)
- they got back together and parents meet each other so I think they are going to marry.
> Si woo is mature at work but very stubborn in relationship. He hates his father and when Hakyung try to interfere he shouts at her. He does not want marriage.
> Ha Kyung is the only character with great character development. She's stubborn too but you can understand her. Of course, she will always be beautiful hehe.

Yujin and Ki-jun
- they are the exes of the main leads. they cheated them so bad
- they act arrogantly like it was not their fault to cheat
- they have quarrels but they became happy at the end with pregnancy (I hate them being happy)

Senior Um
- Low EQ
- almost divorced
- He get back together with his wife

Taukyung and Seok Ho
- seokho is Hakyung's subordinate and neighbor
- they met coincidentally
- they meet more often
- they dated (they are the cutest here hehe)

There are more side stories about their colleagues. I can say that I didn't regret watching it but I will say it doesn't satisfy me. I watched it for Park Min Young. They said that Hakyung is serious and workaholic but they only shown her mistake forecasts about weather they did not show her predicting weather accurately, only in the last ep. They introduced Si woo that he can predict rains and snows with his great sense but they did not show that at the middle of the story. They made the exes as the main leads adviser which I hate. I don't think that the story between the exes is necessary at all. The first 3 episode is interesting but many got bored after they dated. I rated it 8 and that was the lowest rating I've given to the dramas that I don't like. The casts and their acting is good, the general story is good but the plots and side story is not. This is better for a movie. Lastly, I skipped all the parts of Kijun and Yu jin, I just know what happened but all their conversation, I skipped them hehe.

Watch it and decide if it is your cup of tea drama.
