It's kinda sad that the closest to romance we get are the last two pages in chapter 23.
Still a really cute and heartwarming manga.
I'd say the last page of ch 27 has a nice romantic bit.
"Even if it's worn out, or even split in two . . . It's something I got from you. So don't throw it away! got it?"
Awww. I think that's about as romantic as Churio was going to get. It'll do for an end.
Still kind of sad there won't be any more. I got oddly attached to this little gag manga.
