This drama left me with mixed feelings. The journey starts with Hae Jo trying to find his purpose in life and his parental lineage while grappling with a ticking time bomb in his head.

'Mr. Plankton' is such a beautiful and apt title and metaphor for the story. While plankton may seem insignificant in the vast ocean, their lives are crucial to maintaining the ecosystem much like Hae Jo, who feels overlooked yet contributes in his own ways to people around him.

At the start, Hae Jo came across as a brat but as the drama progressed I found myself sympathizing with him more and more. His flaws and initial arrogance gave way to deeper struggles and vulnerabilities, making it hard not to feel for him. The transformation from a seemingly self-centered character to someone with real pain and abandonment was gradual yet powerful. Woo Do Hwan did an excellent job portraying this character.

The road trip part was exciting and the cinematography was simply stunning. However, I wish the show had delved deeper into Jae Mi's character and her own internal conflicts which felt somewhat underexplored.

Also, I loved the bonding and sort of 'found family' dynamics overall in the drama, especially during the second half! The pacing was also better in the latter half, which made it more engaging than the first.

But the emotional weight of the drama is undeniable. Yes, it is not perfect but WDH's portrayal of Hae Jo was so raw and heartfelt. His struggle with abandonment and his illness leaves a bitter-sweet taste in the mouth that lingers.

Despite its flaws, this drama is worth a one-time watch, especially for the powerful performances and emotional depth it delivers.
7.8/10
