I really did expect more from season 2, but sadly it didn't meet my expectations. I was so excited for season 2, I really thought that it'd focus more on Yeonwoo finding his mother as well as Yoohan and on him independently since Hyunjun said he wouldn't be in this season. I was disappointed when they revealed the new lead purely because I loved Yeonwoo and Yoohan's romance, but I was also intrigued since I enjoyed VIXX and I recognized Hyuk. I was curious how they'd incorporate him into the plot.

First, my rating for the story. The story wasn't as good as it was in season 1. It felt a bit rushed. It was like they were throwing things at you for the sake of it. I don't particularly enjoy love triangles so I was glad their love was one-sided honestly. I definitely get that a series being plot-heavy can make it less boring, but it was really just a bit boring and a bit harder to keep up with this time around. The action scenes weren't good at all, and I had a good laugh when I saw them in the hospital because how does Sehyun have casts on like... every part of his body like he broke everything but he only got hit like once.. that just didn't make sense.
I love the plot of the series, it's so unique and I haven't seen a BL mystery series with this type of plot before but the execution this season compared to the first is lacking. I can't say I disliked the chemistry between Yeonwoo and Sehyun though, they were definitely cute together and they both acted very well. Sehyun was definitely adorable, he was like a puppy.

Secondly, the acting/cast. The only thing I didn't like was Hyunjun not being there and the less screentime that Seohoo and Hyogi got. Like I mentioned before, the chemistry between Yeonwoo and Sehyun was cute, I didn't particularly think they were for me couple-wise, but I think they'd be really good as best friends since Yeonwoo is already in a relationship with Yoohan. Yoojun and Hyuk's acting was very good though, I didn't expect anything less and they definitely delivered.

Thirdly, the music. I liked the music from this season. I don't think I have much to say about it other than that lol.

Finally, the rewatch value. Personally, I don't think I'd watch this again. I've rewatched the first season more than thrice, but like I said this season just wasn't really my cup of tea. It was definitely better for others, judging by the reviews, so I'm glad some found good rewatch value in this. We all have different opinions, that's the beauty of it!

Overall, I think a solid 7 stars describes how I feel about this season. It wasn't bad, but I don't think I'll be rewatching it anytime soon unless it'd be to catch up again if they create a third season (hoping they do).
