Since I don't have detailed knowledge of this specific visual novel, it's difficult to say precisely. However, from the title, it seems that it has a connection to a son's friend. It might tell a story full of drama, with the relationship between different characters evolving as the story progresses. There could be emotional moments, conflicts, or revelations that are centered around the situation of being 'okasarete' (entrusted) to the son's friend.
The title suggests that the son and his friend are key characters. The son is a part of the equation as it's his friend involved. There may also be a parental figure who is doing the entrusting. Without more information, it's hard to say who else might be a main character, but it could be someone from the son or his friend's social circle who gets drawn into the situation.
In certain fanfic concepts, Naruto could learn Edo Tensei from Kabuto. Kabuto, having mastered the jutsu, might decide to teach Naruto for some reason. It could be because he sees Naruto's potential to use it in a more positive way compared to how he misused it. Naruto, with his strong sense of justice, would then try to modify the jutsu to be less evil - like not using it to bring back people against their will.
Hard to say. It could be on hiatus, but without concrete information, it's difficult to give a definite answer. Try following the mangaka's social media or the manga's official website for the latest.
