I think I would have hated this show if the cast wasn't as great as they are. I am going to break this review down into parts

Rui/Zong Yi-- I hated Rui at first and thought that I would never be able to like his character, and to be fair I didn't for most of the show. I had a very big problem with the fact that Zong Yi was a minor and Rui was forcing Zong Yi to house him and was also being weird and flirty with him. I thought that they would at least age up Zong Yi before the actual romance/intimacy was happening but Nope. It was important to the story that he was 17 but I don't really like that there was a sex scene when one of them was a minor and the other was in his 20s. I thought the part where Rui was hidden in the house went on way too long and I was honestly getting bored of it, but then it ended. AND THEN HE WAS HIS TEACHER???? I also don't really understand where Zong Yi's feelings came from since all Rui has done for him was help him with homework (in exchange for cake may I add) but once they got together I didn't hate them. Towards the middle of the story, I started to like this couple more and was rooting for them to get back together when Rui was out of prison, but then they pulled the amnesia thing which didn't really make a lot of sense because he was injured from being punched in the body?? but whatever lol. Once Rui and Zong Yi were back together I liked the storyline with Zong Yi's dad having a problem with them because obviously he would his son went to jail because of this dudes gang/mafia/whatever it was. By the end, I was happy for them and thought their ending was very cute. This review seems like I hated their entire storyline and I wanna add on that I dont!! Just compared to the side couple I did not care all that much for their story. Im sure that many people probably loved their story!!

Chen Yi/Ai Di-- For me they carried this entire show and I think they should have been the main couple, to be honest. I'm kind of a slut for childhood friends to lovers and especially in a mafia show like this I was just bound to love them. Ai Di was my favorite character in the entire series. He was so cute but crazy at the same time and honestly very mature for his age, WHICH WAS 18 THANK GODDD why does every show have to have so many minors??? Chen Yi was also a favorite of mine. Him being in love with the boss at first (who was like wayy too old for him idk why nobody told him this) made the scenes between him and Ai Di even better because I never knew when he was just gonna realize that hes in love with Ai Di (which was so so obvious I literally thought they were dating when I started the show) . These characters had soooo much chemistry I was literally biting my nails wondering when they were gonna get together. I was sitting there so sad for AI Di when it showed him celebrating their birthday alone every year TT. I did not like the fact that the first time they slept together Chen Yi was drunk, and then they didn't see eachother for years. I also did not understand why Ai Di went to jail I dont think they ever explained it. After the time jump I loved this couple even more. Seeing straightfaced, always serious Chen Yi try to figure out how to get Ai Di back was so funny (I liked when he gave him the face pillow lmaooo). When they finally got together I was so much happier than when the main couple got together tbh.

I did not care about the two old dudes at all and everytime they were on screen I did not pay any attention to them at all Im sorry. Im sure their story is interesting but I have no interest in the love story of two old annoying awful dudes.

I would recommend watching this just for the awesome cast, and for Ai Di and Chen Yi. It also has some cameos from other Taiwanese bl actors! Overall I definitely enjoyed this series.
