Uuuh so its been like 3 years, just remembered it but not clearly. So it went among the lines of entering this completion and the reward is to grant one of your wishes. But in the last? Round the announcer? Decided to "spice" it up and say who ever ejaculates first loses. Also mentioning that they were in a wrestling ring looking area. So theses two would try to win ofc and will just say that the seme fell for the uke and loses letting the uke win to revive his most important one which lets the uke to regret letting him win but in the end the uke special girl was his pet cat and they ended up going out together. the seme and uke not the cat. Basically said the whole plot ;-; oh well
