MTL - All Things Wrong (Retrograde Gaming) - Chapter 5 You also owe it, right?

A part-time job contract. He became the cold CEO’s imitation boyfriend. He merely wanted to earn a few small bucks and live a comfortable life, but a pity, he was in constant turmoil since then. Well, life had something else for him despite his wishes.“That… beauty, will there be an increase in wages for conversion from ‘boyfriend’ to ‘husband’?”

Growing up in poverty, Sunny never expected anything good from life. However, even he did not anticipate being chosen by the Nightmare Spell and becoming one of the Awakened - an elite group of people gifted with supernatural powers. Transported into a ruined magical world, he found himself facing against terrible monsters - and other Awakened - in a deadly battle of survival.
What's worse, the divine power he received happened to possess a small, but potentially fatal side effect...

The mountain village boy accidentally got the fairy gourd, and he rose step by step to cultivate immortality and longevity.

Ripe elixir, mortal flow.
