Honestly speaking I don't really like writing reviews, but considering that this drama had quite a few negative ratings regarding episodes 18 to 24 I was compelled to write a review.
The drama is must watch for all those romantics at heart who would do anything to get away from the real world to enter the drama world and experience some cute fully moments that pull the heartstrings in a positive manner. The first few episodes (1-17) were quite entertaining, funny, and sweet. The female lead was the highlight in the first few episodes, she was rather cute in a happy way, not the typical female leads that annoy the anger out of us. She was outspoken, smart, and emotional (good way). The male lead was the typical cold tsundra, however, like every Domeneering male leads he too has his sweet side and a crazy yet hot side and negatives which are balanced out by the female lead character.

Now from episode 18 onwards, the storyline can be quite a roller coaster ride with a lot of fluffy moments and resolved problems, both the leads do end up doing crazy, annoying things. But I personally believe that's how real life is, certain personality traits can make people rethink relations, question themselves and others, have doubts as well as do stupid things in love. Adding to this is the age difference, the age difference can sometimes cause a little trouble in paradise for every relationship.

Moreover, A drama can have a few episodes of stupid actions, only then will it be a drama, and these problems actually make the leads grow and mature. It's not something that we viewers can't handle, rather it's okay, the misunderstandings and jealous actions get solved quite early on in the case of all relationships, from that of siblings, rivals, or the leads themselves.

The story of the 4TH COUPLE (SECRET REVEALED ONLY IN THE LAST 2 EPISODES) was super cute! I loved it personally speaking, although it was just one episode long it was real and cute. The Leads relationship had its ups and downs but again it was amazingly cute in its own way especially for viewers who like seeing The old young relationship.
The second leads were the exact opposite of the male leads, it was the young man and older women relationship, again it was sexy. The third lead couple were meh, it talked more about the bond between them than a romantic relationship

Overall, I personally liked the good bits and the bad bits of the drama, ESPECIALLY THE ENDING WHICH WAS EXTREMELY CUTE CAUSE OF ALL THE HEARTFELT CONVERSATIONS. Every drama has it's good and bad, it's actually a balance in this drama, and the character growth is impressive as well.

I would suggest ALL ROMANTICS PLEASE WATCH IT, YOU WILL NOT REGRET IT CAUSE it is CUTE AS HELL
