0 stars, do not come back to this hoping 'it get better'. Despite its name recognition popularity from getting an OVA, this is TERRIBLE. Morinaga and Souichi were likeable background characters in The Challengers, but their entire main story boils down to Morinaga raping Souichi after he (S) gets drunk, and then blackmailing Souichi into more sex (aka, more rape) while claiming it's because he (M) just loves Souichi so much. And this just keeps going for multiple volumes. What the fuck. Why.
Soredemo Ore No Mono Ni Naru
Did not actually read - comments mentioned rape, no thanks.
Best Ending?
Annoying that the guy in the otome story turned out to be S. it was just wierd and borderline assault. The swimming story was fine I guess, but not very interesting.
