S-Rank Harem: I Became My Character with Extra Control Skill

[WARNING: R-18 | Adult content, suggestive and implied explicit scenes]Ryan, a programmer who had always been a failure with women and, because of his job, never had time for dating due to constant workplace exploitation.One month before the release of his company's most ambitious RPG, he decided to take revenge by adding a secret "bug" to the game.A hidden skill called Debt.Every time the support character healed or buffed a heroine, a mandatory debt was generated. An order that had to be fulfilled. And if it wasn't claimed, the skill would execute it automatically.The company discovered the code and punished him by forcing him to work without pay to fix it. Exhausted and on the verge of collapse, Ryan dies of a heart attack before he can remove the bug.But he awakens inside the game.Now he inhabits the body of the Rank B support in a party of Rank S heroines and the Debt skill is still active.Ryan will have a significant advantage, because not only will he gain the normal experience and rewards from leveling up, but he will also receive the additional rewards granted by the Debt skill.With an advantage no one else possesses, Ryan must decide:Will he become a tyrant who manipulates his companions?Or will he use that power to survive, protect them, and become the only support capable of reaching S-Class hero rank?Because this time, he won't let anyone exploit him again.What to expect:Character progression / Harem / R18 / Fantasy / Demon Lords / Worldbuilding / Multiple races / Fantastic creatures / Magic / LitRPG elements / No NTR.
