Many readers are rightfully angry about this couple because of information from the sequel Eien Shika Hoshikunai. However, I think the seme did not cheat. Not to discredit the translators of the sequel (I am very appreciative of the translation and honestly it makes the sequel more interesting), but I think there are some mistranslations. I am basing what I am writing on the Japanese I understand from classes and google translate, so there may be some inaccuracies.
The things I will point out will probably come to light in later since Dekiai Keiyaku is now being translated, but I want to clear this up now since many may drop this series due to the misunderstandings.

I think Reiji and Kuramoto had already broken up before Dekiai Keiyaku began.
On page http://www.mangago.me/read-manga/dekiai_keiyaku/raw/iur_chapter-0.2/pg-72/ Reiji says “In the past, I was Kuramoto’s lover.”
I found the Japanese raws of Eien Shika Hoshikunai on Twitter
https://twitter.com/dear_plus_/status/1199258481062100992 , and the first page matches with this page http://www.mangago.me/read-manga/dekiai_keiyaku/raw/iur_chapter-0.2/pg-117/
It says something like it’s because it’s him (Masoto) that I fell in love. It was the same for you. (Or something, it definitely doesn’t say breaking up)
On this page, https://pbs.twimg.com/media/EKSeK-xU4AAahVp?format=jpg&name=medium he calls Kuramoto his former lover and says the two had such a strong relationship, he couldn’t come between them.
So I think Kuramoto did not cheat and there are some mistranslations in Eien Shika Hoshikunai (which is still a good story) that caused this mayhem.
Thanks for reading all this ╮(￣▽￣)╭
