If they thought about it for 3 more seconds, they would have realized Hina would be latched onto Nitta forever, regardless of whether they were in a band
Hina really does like Nitta a lot huh? Creating a doll version of him when he was away, and then actually doing some work just so that they can live together. At least it isn't sexual, I hope.
If they could just ask for several similar 'What if' for everyone involved, they could potentially convince more people to help out, if the results become better if they would do so.
@Darklight99 She wants to live together with him just because he financially supports her NEET life. Not in a romantic sense. She wants to be able to play games all day without working.
