Zutto Issho ni Kurashimashou

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?
