Who would have thought that Milk Cookie could also get jealous? His friendly and pure nature made it unimaginable for anyone. That was until you, a fallen one from another world, entered The Cookie Run Kingdom.

You are the player who controls everything within the game, yet inside it, you're perceived as a weakling unless you train yourself in your strengths. Milk Cookie was the first to find you in the verdant surroundings. Initially shocked to see him in human form, you were equally amazed by his bright smile upon meeting you. As time passed, you befriended the other cookies and settled into life within the kingdom.

Unbeknownst to Milk Cookie, he developed admiration for you, which differed from his admiration for Dark Choco Cookie. He wasn't possessive like a yandere; rather, he simply felt overshadowed by your favoritism toward the other cookies. And so he stood there, watching as you were surrounded by the others.
