the show is lighthearted. even at the most 'thrilling' moments, the show doesn't really take itself seriously that way. those moments are a shock value at best.
watch if you want a feel good but mildly complicated mildly funny show. the romance is like high school romance x idol-fan romance. fluffy puppy love?.
plot:
it's nothing new. but some elements in the first episode drew me in. like a fl in a wheelchair. i liked her acting. but this angle wasn't explored much, to my disappointment. All other serious topics like suicide, suicide prevention etc are also conveniently wrapped up, and discarded. TBH, if the first ep wasnt so serious-like i wouldnt have watched the show.
romance is the center in this drama. literally, the side characters' arcs are all over the place. There are many 'twists', that seem very unnecessary. They drag the show on and make it very tiring. i feel like the show could've been a lot more crisp.
similarity with extraordinary you:
KHY's character, IS is the heavy lifter of the show. she's running around and doing all of the 'stuff'. others just exist or show up in the nick of time. The tunnel focus on the romance is also similar in nature. There's also no villain per say.
that is why I feel like the target audience of the show must be younger people. like middle schoolers. the pining nature of the romance, the stretched out length, slight sprinkle of danger, whiny dialogue delivery (much to my chagrin). yaah.
nature of romance:
since romance is the centre point, i feel like it deserves a section. Both fl and ml are really into each other. They have good chemistry. I didnt find any glaring problematic sequences of mistreatment or abuse. The ml is green flag. The poor chap is clueless all the time, yet he figures what the fl is upto just by observing her. He's into her that much. They both put the other before themselves, so it checks out. The theme / flavour of romance changes according to the setting. idol x fan, next door neighbor, school sweethearts, longtime flame. Highlights a 'against all odds approach' . "No matter what the situation or stakes, my choice shall be the same". It was heartwarming to watch.
honorable mentions:
Tae song, his arc changes quite a bit. not explored much
In Hyuk, ultimate wingman.
Grandma, attempt of writers to make sense the 'twists'.

If you liked extraordinary you i think you will like this too. Dont go in expecting something serious. Its all just very lighthearted. not serious at all.
