I don't know why this actually nearly made me cry, I think it's because I also have a close relationship with my mother so just seeing the dynamic really made me feel close to the story. I also really like the simplistic story telling and the snapshots of each of MC's life as told by her need to bandage things. Honestly, to me it sounds like everytime the mother calls or she calls the mother, the bandage is a way to signify how the mother helps fix the small incidents MC goes through and is a reminder to be careful and to always take care of herself.
Honestly I really adore this concept! Love how cute yet heartwarming it is!
