And also it's hard for him to say "I love you" which I understand, I have the same issue myself. And if he doesn't say or show that he loves Masato, then maybe Masato would think he doesn't really love him, which is an anxious thought.
Asahi has had a rough life so of course he's going to have some issues as an adult.
It's not that Asahi is doubting his feelings for Masato. He clearly loves him. He is just putting himself down and thinking the worst of himself, which would be to have gotten together with Masato out of convenience. He is going through a rough patch and feeling a lot of negative emotions. When you are vulnerable you start to believe the bad things people say about you.
Don't get me wrong though, this annoys me to lol I don't want this kinda issues between them and I certainly don't want Masato to feel more insecure about their relationship. My boy deserves utter happiness.
