He's very suspicious and to some extent, gives of "yandere-ish" vibes. We do get to learn later on how he sort of became like that but it still makes me feel weird. At some point, I feel like rooting for the other guy though I don't want any more drama in this series.
Other than that, I really love this story and they're sooo cute! I still enjoy reading it nonetheless.
Also, I love Hananoi's blushy face hahah :)
