Hi, maybe I'm too late but this is what I learned from Reddit, quote: "So in the last chapter of the manga, it was shown that Souta was also looking for Poco everywhere in the forest but didn't find him, and then many temple priests and his sister, her husband, his friends were also looking for Souta and found him in a wounded state and his sister was also worried then they cured him. Souta was sad because Poco was gone. The old priest said that Poco will always be with him. And a few days later, Souta writes a thank you letter to everyone and invites them to eat udon

They have Bad ending for both Anime and Manga! Ugh!!
Who is cutting onion rn!?
Despite of Manga still continuing till 2019, author doesn't give us a happy satisfying ending. This so hurt. Really my heart is broken rn.
