Monster Kindergarten is open, sign up now.
Hey, that cute little wolf demon, don't leave. Come and have a look. Food and accommodation are included. I'll pay you five social insurances and one housing fund. You'll receive dividends at the end of the year. You'll have two weekends off. As long as you're good, I'll buy you a gai.
Hey, that beautiful peony flower demon, you come to our college to study, you have a lot of benefits, you have meat every meal, what? Do you want to become an immortal? No problem, I'll teach you and you'll be able to do it, and I'm sure you'll be in the Immortal Class.
Little monsters, I am such a good person, hehehehehe.
Idea: As long as you pay money, the protagonist can cheat and abuse the scum.
