It was hell for the first chapter, like seriously that nurse was a bitch. But then now I understand why he acted like that, the nurse had a sad past that's why he was unable to love someone. And as for Naoki, I'm seriously happy for him he got Ryou by his side and now they're complety lovey-dovey, especially for the nurse, he manage to open up his heart for Yuuji who seriously loves him. Overall this manga was great, but you have to sacrifice your heart first for the first chapter xD
