Do the other characters not realize that you keep coming back, doe this happen with a few people, or is there going to be a whole arch in the future where we explain to them that we essentially respawn? Also I feel that this feature could be both a fun story point as well as an interesting part of the mcs relationship with other characters. Like maybe with certain characters vore scenes become more intimate as things between them progress and as they learn more about the mcs situation. Also If you plan to make this a harem game or give it harem options/routes then more interactions between different characters would be a good idea. I mean If they intend to share the same guy then a situation where the characters all get along can open the door to some fun interactions.
