Reincarnated as a Summoned Spirit (A Slice-of-Life Serial Reincarnation LitRPG)

For most of his life, Ver rarely went outside. Even when he was a kid, most of his time had been spent in his room; it was a hospital room, but his room nonetheless. So when there was an option to sacrifice himself to save his sister, Ver immediately took it. But he found out that when he died, he got to reincarnate into another world as a spirit with his memory intact. With enough points, he could reincarnate over and over again, each time stronger than the last. To gain points, he had to make a contract with a sapient being and grow stronger with them. But if he failed to gain enough points before he died, he would die permanently. However, Ver didn't pick someone based on how talented they were; he picked based on whether or not he would like them. The people he contracted with were not famous, rich, or powerful, but he enjoyed being with them, and that was all that mattered. Even if he had to die because of it, so be it. Living longer and becoming powerful did not entice him at all; he would enjoy his new life to the fullest. Each person he contracted with had their own goals, beliefs, and personalities, and Ver would love and cherish each one. Oh, he also became a milk spirit in his first reincarnation. No way would he choose something basic like fire or water. What to expect: -Each reincarnation will be very long. -Multiple MCs. Warning : -There will be no romance for any of the MCs, but a lot of people see some of the friendships in the story as romantic, which is not my intention at all. However, you can think whatever you want; I don't really care. I just don't see romantic love as the highest form of love. -The story will discuss heavy topics, and while the characters in the story are not normal, I still treat them as people. That means no instant recovery, nor will there be characters who are completely immune to trauma.
