Same vibes
Two characters one of them with terminal illness, and kinda the last journey. I prefer Mr.plankton gor being more realistic. Close to normal ppl life, and not having side story with involvement of other ppl in love story or break up. There was pure love short journey which no one hide their emotion, everyone are honest with their feeling and never act for each other anyway I enjoy both drama a lot.

Both about big brother taking care of siblings, heartwarming, illness
Both brothers sacrifice for their family and have trouble some little brother
