Sorry, but I don't get it. If the guy said goodbye then why did he leave a flower pressed inside the book? And if the guy didn't really mean goodbye then this is just more cliches dropping all over the place. The uke has to compromise more than the seme once again. Such tired BS. Which is more what the translator should have warned us about than that this was a novel with few pictures.
For those who only looked at the images (detailed resume in a comment of the topic below):
Seichirou (black hair uke), an unlicensed doctor, meets back an old classmate Takechi (white hair seme) but ends up repaying him a medicine for his patient with his own body. They were close friends and had a secret meeting place but Takechi had to go study abroad.
Then Seichirou understands that he is in love with Takechi and leaves the house. Takechi was in fact also in love and when he finds a paper, left by Seichirou, with their old secret meeting place, he dashes out of his house.
