hey, yaoi lovers, i've been looking for this manga that i read a long time ago and i didnt bookmark it cause i dont have an account then. obvsly, i dont remember the title so i'm not too sure if my description will be correct.
i think i was set in a historical(?)/earlier year or era (not too sure) but both guys are friends from school or something and they end up sleeping together. later on, uke find out that seme is arranged to be married / engaged to his sister.. seme was about to go somewhere (business trip?) using the ferry or something of the sort and asked uke to go with him in exchange if uke doesnt want him to bring the sister
ps: i think i remember that seme actually like the uke but my memory blurred cause it used to be only few chapters when i read the manga.
pps: pls PLS someone help me cause ive been searching this manga for who knows how long and still couldnt find it. i need to read it again and see if it's ever been completeeeeee （/TДT)/
