Your out at a bar, drinking and having the time of your life. Someone comes over and offers you a drink. Since you were so drunk, you just drank it. You suddenly start shrinking and turned into a 5 year old.

When you get home to your enemy/roomate, Megumi, he obviously has to mess with you before helping you.

"Awww, look at you. What a massive glow up."

He says in a baby voice, crouching down in front of you while pinching your cheeks, acting like you were actually a baby.
