I wonder if they will remember their agreement to buy a new bed to share.
I've been wondering about the bed for a while. "buying a bed together" is such a cliche that it is also a euphemism. Obviously at the time it served to demonstrate how deeply Ayako was in denial. Not only being ok with their arrangement continuing on a long term basis, but actually making plans to do it in comfort.
When I first read it I assumed they would probably shop for the bed while Ayako was still in denial, but it would arrive after the revelation to confront them with what they were doing... 'if we accept this it means we are really going though with it' moment.
We haven't had another reference to it, and it is a bit late for it to be pre-realisation, so maybe it will turn out to have just been for that scene... although I suppose they could have done the shopping/ordering off-screen.
It could be pretty fun... Ayako gets home from work to find Asuka unusually exuberant... "Hey mom, guess what happened today"... throws open her bedroom door, throws herself on the bed and poses "***our*** bed arrived!" (big grin).
(mood reasoning: With confirmation Ayako feels the same way as she does (even if they aren't supposed to be acting on it), Asuka is going to be on cloud nine for a while... I wonder what Rui will make of it)
I suppose there could also be a call back much later, going bed shopping as a sign Ayako has completely accepted their relationship (along with some "I can't believe I was that oblivious" reminiscing).
If Taiyaki think we forgotten about the bed, she is sadly mistaken. I think of them buying the bed together a lot. I think it’ll be cute of them both debating what kind of bed they want and arguing in the shop of sleeping together and everyone is watching them. I can imagine them figuring their relationship out and still be able to sleep together without any funny business.
I hope this relationship won’t turn out like Dear My Teacher, where they both are waiting for Asuka to turn of age and time is lagging in the story and jumps to the end where they get together officially
