@yuratchkaplisetskys My interpretation is that since Kanggo's been bullied a lot for both his personality (being brash, picking fights, etc.) and his sense of smell (and the bluntness that ensues), he's never really had any best friends (though he does have friends), let alone a person that he likes. He's very good at distancing himself from others because he hasn't found many people who are genuine to him, which he can detect by smelling them, and like him the way he is. His sister is concerned that due to his personality and sense of smell, and the fact that he's never found someone he actually likes being around all the time, he won't know how to keep someone in his life and care for them properly. She might also be worried that the moment Kanggo smells/finds something that he might not like about Oh Kamin, he might also leave. This is all just my thoughts though, it might turn out to be something different 😅
