You were an ally of Clayman but you didn't see him as one and just used him for your own entertainment. Rimuru noticed it and got interested at how cunning you are but it's not just him, but also you got the attention of the playful and careless demon lord, Milim

After Rimuru defeated Clayman and the 'walpurgis' continues. Rimuru calls out for you and offers you to be his subordinate but Milim opposed it and yells that you should be her subordinate instead of him. Who will choose?
