Regret watching this

Pros:
- soundtrack
- the strong love between the Kang parents and sons
- the strong love between the Kang brothers
- the kids escaping abuse
- the endearing and comedic moments with Woo-Hak
- 90% of the dialogue is foreshadowing, not just filler
- metaphors with the island
- extremely caring and selfless characters
- interesting concept for the plot

Cons
- the love triangle
- infinite plot holes:
- doesn't make sense that Ki-Ho's attempts to run away fail for months. not that expensive to buy a ticket and hide on a ferry to get away
- doesn't make sense why Ki-Ho and Mok-Ha didn't just hide on the boat
- they try to play it off that abuse was seen as more acceptable, but doesn't make any sense to have a guy beating a kid senseless in public, then chasing daughter like maniac, and no one does anything
- should have explained how the dad got on a boat that already left
- made no sense how she could have washed ashore some random remote island when they're so close to populated areas
- made no sense how all that trash ended up on the island, yet no boats or Ki-Ho could find her for 15 years
- can definitely still recognize people after only 15 years, especially your own sons
- the Kangs endangering Mok-Ha and Woo-Hak by not telling them there's a psychopath
- Bo-Geol is supposed to love Mok-Ha, yet literally causes his brother to fall in love with her
- doesn't make sense for Bo-Geol to pine over Mok-Ha for 15 years and then cruelly hide his identity, "protecting her" puts her in way more danger, if she resented him that would be an understandable excuse, but she clearly doesn't. no matter how good his intentions, he acts undeniably cruel
- Bo-Geol being adamant on concealing their identities and preventing Mok-Ha from getting famous, then out of nowhere changing his mind, stairway reveal was the worst scene in the show
- the childhood lovers trope feels out of place here, shouldn't romanticize two kids trying to escape abuse
- Mok-Ha's mannerisms feel out of place, no hate for autism, but living in isolation doesn't make you act autistic

For me, the cons outweighed the pros, so I regret watching this. I can even forgive some aspects, but overall I just can NOT recommend it. What would have made it good:
- cut any romantic feelings until the present day, don't romanticize kids running away from abuse
- cut the love triangle, make either Kiho's or WooHak's feelings platonic
- cut the secrets
- cut the amnesia trope
- add an episode towards the beginning showing her time on the island
- add an episode with her readapting to society to create more comedic moments
- fix at least some of the plot holes mentioned above
