Hear me out okay. I really enjoy the dynamic of their relationship and the manga is actually really cute. The characters standalone are also quite cute in personality and design, I love the artstyle and think it's adorable. HOWEVER, it might just be a personal thing but I hate hate hate the type of stories like this where I feel likethey've made the characters siblings for no reason, I know they're technically not siblings but it gives me the ick. In my mind whilst reading this manga I feel as if I have to simultaniously make them out to just be childhood friends or somethingin my mind as to not feel kinda uncomfortable. The manga is solid, I just hate the whole "siblings but not siblings" shitck.
