Total fluff out of a lovesick teenage girl's play book. ML's a full time doctor, a voice actor at least part time, sings like an idol, cooks like a chef, speaks like a therapist AND never dated. He'll love this girl for years only based on her voice and music without knowing what she looks like but thankfully she's equally hot and pure. That characterization right there already puts this drama in the unplausible fluff category.

It's a very slow & mellow drama with uninteresting interactions between the leads but both are good looking.
The supporting couple is cute too.
Both couples are with significant age gap and maturity gap making the relationships even more unbelievable. Age gap is not noticeable when both people are working, but one is in college & one's been working. Even when the age gap is not a big deal the maturity gap feels huge.

TJC fans will probably watch just to hear his voice. Most of the time this drama feels like a one giant cooking music video.
