I agree, except I think that Kou suffered just the right amount for toying with Shinobu. He suffered not only physically but he also suffered very deeply emotionally. He had to work hard to gain Shinobus trust again and the constatnt rejection and distrust from Shinobus side for sure made him go through an emotional rollercoaster. Notice how many times he went to meet Shinobu just to try and convey his feelings. If Kou suffered less I would be dissatisfied, but considering what he's gone through I feel completely satisfied that Shinobu gave him a second chance
I agree with you too....I think Kou's emotional suffering was done pretty well....
I wudnt say Kou worked hard to get Shinobu back but he did do what he cud do best.....in reality if someone suffered to the point of getting admitted to a hospital for a week then it is pretty serious.....and I admire Shinobu for habing the courage to leave and having even more courage to give Kou a second chance. ....I hope cheating yaoi mangas in the future follows this kind of route than just the uke plainly forgiving
