Yang Miri

Yang Mi-Ri (sometimes stylized as Miri) wants to see porn and mosaics only make her more curious.

She wanted to see porn in hopes it would help her grow faster, based on something her dad said.

She wants to get a bigger chest and drinks a lot of milk to help with this.

In chapter 33 the bust is first measured of 3 other girls
 * Kim Na-Young, a girl with short hair similar to Miri but who is different, 85.3cm
 * ? her friend with the black hair tied to the side of her head which was only 83.2cm around.
 * Sulgi who was 95cm

Finally when Miri is measured she is only 72cm around, which girls think is cute
