Thanks for the chapter. I'm assuming that the tomboy side of Wakaba is an act to stay closer to Daiki due to his apparent fear of women, so it makes me wonder what will end up happening. I think whether or not Daiki gets used to Wakaba's feminine side by the time they start dating will determine whether this manga will end at the confession or continue past it.
If Daiki gets used to Wakaba's feminine side before they start dating, then I think the manga will end at the confession. This is simply because if it doesn't end there, then the manga will have to change its premise from "Cute girl disguises herself as tomboy to stay with gynophobic MC" to something else. Admittedly, there have been manga that discard their main premise partway through, such as Kaguya-sama, but they are far and few between.
On the other hand, if Daiki doesn't get use to Wakaba's feminine side before they start dating, then the story can evolve to focus on the hijinks around Wakaba trying to maintain her tomboy image whilst dating Daiki. I personally think this option is much more likely than the other, and can already imagine Wakaba constantly trying to maintaining the fine line between wanting to do "couple things" and wanting to maintain her image as a tomboy. Although I would still much prefer that it ends with Daiki getting over his fear of women, rather than an open ended "will he, won't he" that seems to be all too common.
