If Ruka's project is also the series' final arc, expect Ruka revealing Kazuya she's going 18 in august and saddling Kazuya with a marriage proposal and Kazuya instead of rejecting her, accepting her because he thinks she's awful but feels like he can be with her nevertheless. Not an "i love you", but more of a "stay with me" proposal.
Misery porn just to humilliate Kazuya further.
