I was terrified to read this at first because of the comments, BUT GOOD THING I READ THIS! Isumi (the Uke) is TSUNDERE; his character is naturally the short-tempered type, but I can say that he's definitely head over heels for the Seme. Some say that he's using Enza (the seme) for "CONVENIENCE" or "SAFE choice." Those are not true!! He loves and cares for him very much. Isumi has been involved in unrequited love for his friend with benefits for 7 years. He thought that no one could ever be in love with him, and so he didn't want to give his heart to anyone, but because he found out that there's someone who truly cares and loves him as well, he stood up for himself and rejected and let go of the one he loved for fucking 7 years!! It's not that easy to do that! I just don't really like the way the author portrayed it, and many people are also mad about it. But if you really understand the character of the Uke, he didn't just let his fuck buddy take advantage of him. From there, he had a realization that he should finally end things and let go of his feelings so that he could be free from the shackles that were holding him back. Also, although ambiguously, the couple had also talked about it.
