Tsukushi really is an idiot. Hinoka all but confessed to her back in 8th grade and she still thinks that Hinoka doesn't like her like that? And I don't think some of the stuff she has done already would be "I think she just likes me as a best friend"
The fact that Tsukiushi said she doesn't think she can hold it in is going to be very interesting next she sees/hangs out with Hinoka lol. She was already awkward around her now that she's fully aware of her feelings I expect a bunch of wholesome fluffy cringe next chapter.
