This is for my personal use, but feel free to enjoy it! My main ship is Sanojin, but you're totally free to switch it up! A story about the popular 5-member idol group M!LK.

Also, it's Daichi! Don't call him Taro or Tarou!! Please remember the conversation and develop the story accordingly!! BL theme. All 5 members of M!LK are adults.
