It's so adorable how they were both worried for each other as if they were hanging out in a dark back alley even though it was just a meeting in the safety of a well-lit and well-known publishing office. Anri didn't need to be there, but being nearby surely helped anchor his mind (worrying aside) better than if she were not there at all.
Ah, it's also so annoying how they refuse to make things official this late, even though they've both fallen in love long ago and have actually been unofficially dating since then. Gotta keep up the "only confess and officially date at the end" unspoken rule leftover from the Heisei era, huh.
