The Dating Sim's Trapped NPC

Adrian's plan was simple: survive quietly as a side character in the dating sim he was trapped in. But his new System had other, more indecent plans. Now he's forced to complete shameless quests that push him into the arms - and beds - of the game's most powerful heroines. Every embarrassing mission is a step closer to survival and a step deeper into a perverted harem he never wanted. These women could kill him with a single touch. What happens when they learn he’s just a puppet for a lecherous System?
