This chapter really hurt 😭. Kudos to the author for writing such a compelling story. Normally when something like this happens in a fanfic it usually feels forced but it feels so well written here. It's sad to see Atsuki die but I guess it was kinda inevitable.
You know, the protagonist could have a harem since if he can copy his Uchiha blood lineage and so on in his genetics, he could create a new clan and obtain more powerful nymphs in his line for the future.
