About
You’ll likely enjoy this if you want a quiet, life-affirming family drama focused on everyday bonding and feelings rather than big events, similar to Still Walking or Like Father, Like Son; Not for you if you need fast pacing or constant twists.
Pros: gentle, heartwarming sisterhood; beautiful everyday moments; strong performances | Cons: very slow pace; low on plot; can feel uneventful
