A realization about grief in Solanin and Look Back: Carrying the souls of the ones we lost

I read solanin from Inio Asano a while ago and Look back by Tatsuki Fujimoto recently, and I noticed something that I'd like to share. I will warn the users reading this that this thread will contain spoilers about what happens in both mangas

At the end of solanin, Meiko picks up Taneda's guitar, plays the song that he wrote but never played out loud in front of a whole crowd, and at the end of Look Back, Fujino picks up the pencil again and starts drawing. These two endings have an emotional parallel. Humans grieve very differently, some pray, some cry, some laugh, some isolate, and some look for distractions. My point is grief is different for everybody. But Meiko and Fujino grieve in the exact same way. For Kyomoto, drawing was a big part of her life, and she enjoyed and loved doing that, and for Taneda, it was playing the guitar with his band. These hobbies weren't just hobbies, but also physical extensions of who they were. Fujino picking up the pencil is not only her starting to draw again, she's doing it because it connects her to Kyomoto's soul. Meiko picking up the guitar and singing solanin on the stage is her connecting with Taneda and showing the audience a part of his soul. They grieve by holding onto the heaviest parts of the lost ones souls and carry them forward through their actions so they never truly vanish, and I think that is an incredibly beautiful concept.

What do you guys think? Did you notice this parallel when reading these two masterpieces?
