The MC seemed like he was weirded out by the situation at the start ( like any sane person would ), but he just did a complete 180 and is okay with "being a dog now"? I was hoping the transition would be smoother, it feels too sudden.
@piay123 Yea, it feels like the author wanted to create a tense situation/drama but at the same time he couldn't commit to it while maintaining the manga's lighthearted atmosphere, so the resolution was rushed to return the story to its status quo.
@ShadeLights I feel like he's a little brother to her. The age difference is just too much, just try to look at it from her perspective - he's a highschool boy, she must be like 10 years older than him.
