This is one of the best dramas I've ever watched. It's definitely one of my top 3 favorites.
Story: 9.9/10
The only reason why this doesn't get a 10/10 is because I didn't like some of the ending. Overall, the drama didn't have many fillers and it was really relatable and heartwarming. The character development in all the characters was perfect. I liked how the drama didn't just focus on the romance but zoomed in closer on the family relationships and friendships that grew alongside the couple. It was so deep and sometimes I wanted to jump through the screen to slap a person or give someone a hug.
Acting: 10/10
The family relationship between Li Jianjian and her dad WAS SO REAL. I could've mistaken it for a real father/daughter relationship. Tang Songyun's acting was on point (as always), though 30 she could portray a 15 year-old and you wouldn't even be able to know her real age. Song Wei Long was a little bit meh in the beginning but in the end I could really feel his emotions. Zhang Xingcheng was so goooooooood. There were multiple times where I wanted to sob because of how wonderful his acting was. All the friendships and family relationships were very realistic, relatable, and believable. I could go on and on about how good each and every character was at their portrayal but that would take forever.
Music: 10/10
I normally skip the openings to watch the drama but for all 40 episodes of this drama, not once did I press the fast forward button. And I tried searching the OST up on Spotify too (it's there). I just loved it that much.
Rewatch Value: 10/10
Heck yes. I already rewatched it again and I'll prob rewatch it like 10 more times and I'll still want to rewatch it.
Overall Rating: 10/10
There's something for everyone in here. There's females supporting females, there's healthy (and toxic) family relationships, loving bromance that will make you laugh, and a sweet romance. There's totally gonna be a lot of SLS though I promise you that. But I would definitely recommend this.
