>Her Parents
Seems Ruka's family is a single parent family.
Ruka is hiding her boyfriend from his mom, remember that.
Kazuya won't be well received by Rukamama bc of the 4 years age difference if happens..

The other thing that could actually happen is Ruka stalking him to his new flat by the next sunday and surprisingly welcome him once he comes back from his parents place. There was a moment in the Epos (not)sponsored(at all) "date chapter" where Ruka was checking his phone trying to look for strange shit. So she may have found Kazuya's new address.

If she does that, then she confirms herself as the Yuri of this story. A dangerous stalking creepy menhera.
