I've just got a new theory as to why Houjou is attracted to Youta.
In the committee of her subconscious mind:
"We need to have a plan, we're too lazy, if things continue this way we'll end up as another girl-failure, halfway melted into the tatami mat."
"We could, maybe, better ourselves?"
"NAH! Too much effort."
"Ok, so what about getting a boyfriend? Someone serious and responsible and hardworking who will care not just after us, but also for us. Who won't hesitate to drag our ass out of the kotatsu to avoid us becoming something that can be picked up with a bucket."
"And he's gotta be cute as well."
"And where pray, are we supposed to find such a perfect specim...? Sense of smell! Will you stop sniffing so loudly? It's distracting!"
"Sorry, but I smell prime husband material."
