Damn, already dreading the future chapters. For her to be waiting 4hrs and to get not a single reply after being stood up is nonsense. Thats not about being put 1st Hikaru, thats about not caring about u at all.
Honestly, regardless of Hana, i dont like relationships based on convenience either. The fact they are married for 2 yrs but Harutaka see the need to spy on her makes clear their marriage is not healthy.
If anything, at this point im hoping for an ending where Hikaru gets rid of both but gets to be happy by herself, not the empty longing for a ghost nor being stuck in this weird marriage.
