Zutto Issho ni Kurashimashou

From [Fujoshi Bitches](https://www.mangaupdates.com/groups.html?id=5619): It was definitely out of the blue. Manato, my favorite brother, is adopted?! Even so, I still sleep beside him, just like when we were little, because I couldn't leave the brokenhearted Masato alone― His slender waist leaning against me; His hair which feels so soft and fluffy and his sexy expression when looking at me… I can’t think of Manato as my elder brother!! Growing up under the same roof…A heart-warming love❤A story about all of the five brothers of Takasuga family❤
