I'm looking for yaoi manga about propably mentally ill boy (uke). Care of him his brother or cousine, propably. I saw only one chapter - boy escaped and when brother found him, boy wet himself in front of brother. In the night brother and boy sleep together in one bed and they had tied a string on the wrists, because brother feared that boy again escape. Ill boy wore kimono/yukata, brother riding a bike.
Please, help.
I really want read this manga, but I don't remember title and i can't find this. 😢
Sorry for my English. 🙁

It reminds me of Tourou no Ori but some details seem to be different...

Yes, this is it 😃
Thank you very much 😀

I know, I wrote "brother/cousin" but they are not family. I saw only one chapter, so I could make mistake.
But you are amazing 😀

Thank you
