Smokes, dominantly possessive, over a certain height, and handsome. It's interesting that the ML's soul has being following the MC without remembering that they're lovers or anything. MC only realized at the... 4th story?
It's Loulan, a Sand Golem, that I feel is super awesome. His interactions with the MC are awesome. Their first battle together... uwu I dunno, but I feel that he'll eventually die or something... it's just a feeling.
I could've sworn there was a reference to WOC too... Was it Wei Sheng who was briefly mentioned? Eh.
He saves some women though. He's rather popular too. He likes women, but no action so far. Also, some other dude's science poetry was hilarious.
Kinda like Library of Heaven's Path, but nerfed. He has a library inside his head.
a mushy corpse
(slightly tsundere) Potential water spirit king candidate following the dude. Not annoyingly though. Oh, and the reason for his time-travel was mentioned vaguely. I hope MC finds out all the details.
The seemingly main girl is nice and all, but the reason for Roan and her to fall in love is kinda meh. It's fate???? What the... At least they don't immediately decide that they're in love and swoon together, but still. Their romance is interesting though.
Not really a spoiler, but he's clearly a dude that got transported over from "our" world. A hardcore gamer/adventurer who plans out everything almost perfectly. His one fail so far was hilarious though.
The MC isn't really a front-line attacker, more like a meat shield that attacks in a special way. More importantly, he's an adventurer and his schemes and strategies are more OP than his defense.
