MMM-005 - Mei-chan's youth diary: Spoiled Mei-chan is with her brother again today. Time to graduate from being just a little sister!

Mei-chan is an innocent, angel-like girl. She's munching on snacks while wearing her brother's oversized shirt. When he pets her head or pokes her cheeks, she just looks up with wide, curious eyes asking, 'What's wrong?' But seeing her like that in her pajamas... things are starting to get a little heated. Is Mei-chan feeling something strange now?
