Similar to the author's previous works the plot for the manga is heartwarming. Taishin choose to move to Tokyo after being comforted by Taishin when his fish died to thank him, but he unfortunately didn't decided what he would do after that welp 🙃. Taishin might have a cold demeanor but through his actions it's clear that he's more thoughtful and caring than one might believe at first. The dynamic between the two is so cute, it's unfortunately rare to come across BLs that relationship based on consent/ mutual respect and this is one of the rare ones that does have both. Only 3 chapers of the manga are published as of this July 2021 but I'm sure Takara no Biidoro is going on my 'favourites' list.
