I especially love the grandson–grandfather relationship. The way ML uses his body language to express confusion, teasing, love, and every other emotion is something I really enjoy. I don't know if that's his natural body language or if he does it specifically for the character, but it works perfectly.
The friends-to-brothers-in-law dynamic is also great. Everything about it feels positive and heartwarming—the family relationships, the happy atmosphere, and the chemistry between the couple.
I've watched the first part of all the different versions, and I liked them all. This is the only version that has a second part so far. I definitely recommend watching it—you'll love it.
