I always love how people say slow burn if after nothing changed after 10 chapters ¯\_(ツ)_/¯. You know it's a double edge sword, yes if someone is here to speed up the yuri will come faster but remember that 90% of those yuris will end shortly after the MC start going out. So don't expect much more if it work. Seriously, you can call it slow when it's only the 8th chapter. Also i already forsee the comments "see she was not a rival", yeah buddy but we didn't know before so it's normal to assume things.
