[Pure-Hearted Half-Blood Angel Top × Unhinged Snake Demon Bottom × ABO]
Lumira is a half-blood angel lying low in the human world, bound to a Soul Handbook System and with a life countdown hanging over his head.
He redeems lost souls among humans, doing one good deed a day to extend his life. His progress bar reaches 99%, and he's just about to wrap things up safely when...
[Ding! Congratulations, Host, on unlocking the ultimate hidden mission!]
[Mission: Win over your demonic nemesis, Sirian]
[Note 1: Your target once killed you with his own hands]
[Note 2: An extremely dangerous personality coexists within your target]
[Note 3: You must take the initiative]
Lumira fell silent for a long time, an Omega suppressant between his teeth.
...Sirian? No way.
Wasn't he the Alpha upperclassman he'd been secretly crushing on all this time?
He never imagined that the upperclassman who was so cool and distant, yet had pheromones so intoxicating they could knock you out, was hiding the true form of a pink-and-purple, two-headed snake demon.
Lumira didn't know that Sirian had been watching him from the shadows long before Lumira thought he'd perfected his disguise.
This unconventional Omega often gave off familiar Alpha pheromones, like a provocation, or perhaps an invitation.
Sirian couldn't help getting closer, then completely lost control when Lumira's heat hit unexpectedly.
Sirian: He's pretty. I'll look at him a billion more times.
Inner personality: Let him mark us... Hurry.
Sirian's fingers brushed over his back.
"Junior, it looks like there's something on your back."
"There's nothing there! Stop touching me!"
Angel Handbook, Rule XX: When winning over a demon, turning the tables is essential.
When a serpent's tail coiled around his waist and that deadly voice whispered against his ear, it was anyone's guess who was winning over whom.
