Bro, don't be wierd.
This can either be interpreted as:
『Magma likes long hair better』
or
『Magma likes long hair because it makes Chiaki look smaller(like a loli)』
I think it's the former(hopefully).
And since their intention Isn't exactly clear, I think it's better to not judge too quickly.
i like long hair in general, there's some charm to it, petite isn't eactly loli, more towards smol and why? i prefer cute, wholesome relations over a sexy milf neighbour
