I May Be Your Big Brother But I Want You To Be Sweet On Me Adult

Being an older brother is a lonely existence... Kanata, the older brother, has always been taken advantage of by his arrogant younger brother, Keita. To relieve his daily stress, Kanata works part-time at "Little Brother Cafe", where working men, who are sick of this dog-eat-dog world, pay for young guys to act as their younger brothers and serve them.
Even though Kanata can't tell anyone about this job, he's happy to have his "older brothers" (regular clients) call him "cute" and say that they "love" him. But then, one day, Keita finds out about this part-time job...!
