Maybe something like "facing your fears" for character development or something?:)
She was the trigger, so I don't really consider it twist or unexpected. He'll have to deal with her one way or another to fully resolve his problem.
It was kind of unexpected for me... to be honest I didn't see that coming, she appearing and less in the way she did. For me it's kind of forced? Maybe is that, I still don't buy how all of the sudden Ueda came back to the story. But hey, it's my impression as a reader with expectations and all, very subjective as well.
but his fears were resumed in the list, right? Or maybe, the ten issue in the list has something to do with her?? Mmmmmmmmmm....OH...
Oh I meant she was like the Big Boss of his fears, like the main cause of why he had those fears listed in his notebook to begin with.
"Big Boss of his fears" lol... nailed it! Well yeah, she is...kind of. There were something unusual about Shirotani since he was a kid, she pushed him to the edge of realization that he was indeed unusual but not in the best way. Still, I think it's more complex than that (for me, he was having a little of Oedipus complex and shit went down with her "intervention" in the worst possible way). So, now from this POV if the ten thing in the list is something related to her/his dad (I believe it is something regarding with the old man) kind of have sense she coming back again to the story, I guess. But all we have to do is wait.
Lol sorry, currently playing Metal Gear. That 10th item on the list is so elusive, remember that chp. where he was about to tell Kurose about it but was interrupted? I wanna pluck out Shirotani's ntbk out and have a look in it.(╯°Д °)╯╧╧
You know... after all that has been said about if it was slut-shaming and all that, my concern is that I still don't digest why Sensei decided to bring her at this point of the story...I know I've said before that I trust Sensei, but after this chapter I'm kind of bewildered if this "twist plot" is going to make good to the story, and frankly (and with all due respect this is my very personal opinion) I think that Sensei is walking very near to the cliff where she could fall to the cliché storyline with Ueda being the evil witch that don't want MC end together, I mean this was too good to begin with and has a great potential and truly I'm kind of feeling this is getting far from the original concept. To be completely honest, I hope she kind of forget Ueda exists and use her as an excuse to Shirotani finally speaks to Kurose about his past and how much damage she did.
You kind of know what's going to happen in yaoi stories in general, but is how the mangaka can be truly original with the plots to give you what you expect in the way to never expected to happen, and I sense that from the very beggining with this story. Now, IDK anymore...
Peace!
