Gacha Game Girls Are Obsessed With Me

I was possessed by a gacha game as a shop owner, not the main character.
In order to prevent the destruction of the game world, I must clear the tower.
For the heroes who will clear the tower, feed them potions to level up. Cook for them every time they clear the dungeon. Invest generously in growth materials to help them rank up. Rebuild the collapsed guild house and give them a place to live. Give them a massage when they look tired. Encourage and praise them when they are having a hard time.
Make them equipment at the blacksmith shop and dress them up. Hire a costume designer to create high-performance standout skins and dress them up. Invest generously whenever you accumulate favorability items to meet the conditions for equipping exclusive equipment… … . That’s all I’ve done insignificantly.
Heroes?
Why are you looking at me like that?
I’m a little scared… … .
