Short Review:
I normally enjoy a BL with a music theme, and Tae Yi is such nice eyecandy (Ji Ho Geun, call me anytime), but rating this one was difficult for me.
I loved that the music theme was jazz here, as that's different from the normal rock, pop or indie.
The last kiss was beautifully done and gave me all the butterflies.
Se Heon and Tae Yi had a cute dynamic in their good moments.
However at the same time both Joo Han, and Tae Yi were major red flags and I don't think the reasons that were given were justifiable, or made either character redeemable in my eyes.
