Last page she did not say "i dont have a boyfriend for now" but rather "i dont have a boyfriend right now". Which also explains the first page of next chapter when Rokka is thinking about how Suzuran had a boyfriend in the past. Also i am glad it got cancelled. It started out so well and then you just had to do this het°°°°. Sure we dont know if Suzuran just said it to make Rokka jealous or something, to make Rokka move, but this kind of het°°°° is just not something you should do if you want to write yuri.
