Don't be fooled by the fact that it has two episodes, it was an amazing miniseries.

This is my first time watching anything from the two leads and in the 1hr 15min that they had, they phenomenally did amazing. Jungmin's voice is honestly amazing and I found out that Sungchul [the actor for Jungmin] was a musical actor so no surprises there. Chaeyeon's and Sungchul's acting was on-point and I think that they portrayed the characters perfectly.

It was the perfect music miniseries that I was looking for.

Do I suggest watching it? With my whole entire pride at stake, yes I do.
Will I rewatch it one day? Without any doubt, yes I will.
