What is that manga?

I remember a manga where the uke was masochist. He gifted the seme his favourite book (which was about stars or something) because the seme was beautiful like the stars.
There was also a scene where the seme went a little overboard and the uke had a busted brow.
They kinda ended their relationship but the uke was like I'll always wait for you. Then they saw each other again outside and got back together.
Do any of you guys know the name of this manga?
