the movie starts in a random small village, they don't have any roads connecting them to the next town or souel and only had a railroad that reached them through a bridge
it then starts showing us the life of a lazy highschooler that starts taking private lessons from the prettiest girl in class, and I thought it'd be an old school type of, school romance like 2521 so it was a bit boring (the movie not 2521)

but then the real twist happens. I was a bit confused mainly cuz of Park Jung Min, the 35 year old failing to look 18, he's a good actor, but to cast him after showing the tiny Kim Kang Hoon, who can easily be his son, made it hard to understand for a minute xD then after noticing the sister that didn't age I thought this was a scam movie.. then after the kid vr was brought back, as flashbacks, I started wondering if they were 2 different people with 2 similar looking sisters

now I do admit I didn't pay much attention in the 1st half for those reasons. it felt messy and cheap


until the twist happened... and they showed the both vrs pictures. with a missing SISTER! and it hit me. she died and that was when the waterfalls started till the last minute of the movie T_T
the events of the past. the acting of Lee Sung Min, the reasons and action of those actors, it was all so devastating..
the 2nd half was honestly pure emotinal gold. it was shocking, yet full of hope, redemption, bonding, understanding and heartwarming sweetness

I thought Tae Yoon was a tough love type of dad, but he was so vulnerable, so fragile, so soft.. again casting the 35 year old one thinks he left his son for years but it was around 10 years, tho again a bit much, but he held on to so much self loath he couldn't look at his son again
the moment he got angry at the paper cuz he didn't want his son to be hurt. the moment he forced him to go to souel, their trip, his pure joy over his results (my favorite scene T_T), Jung Jun Kyung confessing that he went to the beach to stop his dad from suicide, junkyung and Bo Kyung "hugging" their dad T_T, their farewell, and in the end the most hilarious ending that just made this little movie even more preciousT_T
