how after like a few (like more than 3) cases, MC finally thinks to ask ML for his name. Like dude, you've been staying in his house for at least a month and are internet friends. Oh ya, ML is his internet friend, I originally thought it had to be a closer sort of friend e.g. schoolmate for MC to so shamelessly go and stay over. Also, ML kind of sometimes tease MC which was very cute in my opinion.

in order to save MC from who I think is the main antagonist, ML ingests a poison, MC wakes up in the hospital, runs back to find ML but he's not there and is told by the ah bao that ML said he will be gone for a while and not to wait for him then when MC asks how was ML, ah bao said not good because he was PUKING BLOOD. So it basically ends with MC waiting for ML to return. Just hits me right in my heart.

There's this moment in book 3 where MC is trapped in this dream and apparently the dream demon will take on the form of MC's most precious person and it turned out to be ML. So there's definitely hints of something but nothing overtly romantic, more like platonic soulmates???

ML is like an ancient demon. He fought with this other ancient demon like many years ago and in an attempt to recover, that bad demon possesses this human boy's soul so that the bad demon's energy will slowly come back and the boy's soul gets reincarnated over time. Initially, ML obviously wants to kill the boy to kill the bad demon but he couldn't do it. Killing that bad demon means the boy's soul will forever be gone, unable to return to the reincarnation cycle. So ML follow's MC's soul through each reincarnation till the current one. And this is when bad demon finally recovers enough energy to come back and in doing do, will kill MC. ML is weakened significantly over the course of the 5 books due to saving MC so he will not be a match to bad demon. MC finally regains the past memory after nearly dying when bad demon takes over his body and severely injures ML. So to prevent bad demon from harming those he love, MC drinks the poison water to kill both bad demon and himself in the process without telling ML. So turns out ML uses his some kind of spirit? in exchange for MC's soul to enter the reincarnation cycle but in doing so he loses all his powers and becomes like a human. So the ending is basically MC in his next life as a child meeting ML and promising to meet again when MC is bigger. DOES THIS MEAN THEY ARE ONLY TOGETHER FOR ONE LIFE? I want them to keep reincarnating and being together... I wish it was happier.
