SANO
'Sumire see's something good in me too, if that's the case then maybe I'm not truly a bad person. I have made so many mistakes. But, I can still fix it can't I? I can feel my heart healing, and these days I feel like a better person.'
The bitterness and jealousy he had towards Mashima has also calmed down. It helps that he hasn't been around his grandmother much. Being away from that toxic environment has helped him process his own thoughts and start think for himself, without others clouding his judgement.
Mashima and Terashima, neither of them are bad people. Even though there was a time Terashima was in a bad place, and thus the rumors. He isn't like that now.
'The reason being, Sumire. Just like Sumire has influenced me and made me a better person, the same goes for Terashima.'
That girl really does have a odd ability to change the people around her.
