Haruka sort of confessed. In chapter 185, she gave Kanae a note and told her to read it when she was alone. It said “I love you.” Nothing much has happened since then.
People seem to be misunderstanding why Haruka offered to help Michiru study for Physics. I really suggest re-reading chapter 175. Michiru unintentionally barged in on Kanae and Haruka having some quality time together in the library. That’s where Haruka learned Michiru needed help in Physics. And that’s where Michiru figured out how Haruka felt about Kanae. Michiru quickly left once she figured out the situation. So when asked to take a picture of Haruka and Kanae, Michiru knew exactly the kind of photo that would mean the most to Haruka. In thanks for Michiru’s kindness at leaving so quickly in the library and of course the beautiful photo so full of Haruka and Kanae’s honest feelings for each other, Haruka offered to tutor Michiru in Physics.
I did not interpret it quite like that. I also remembered chapter 175 instantly when studying physics was brought up, but my understanding of the situation is that Haruka felt at least a little bit guilty in addition to what you have already written. Michiru genuinely just wanted to get some help on a subject she is bad with, and Haruka reacted relatively awkwardly (in a "you are bothering us" kind of way), so Michiru left (while simultaneously cluing into their relationship).
Michiru looked relatively unbothered by Haruka's behaviour and if anything, she looked happy at reading the situation between the other two girls, but there is no way for Haruka to know that.
So when Michiru was kind to them with the picture, Haruka felt both grateful and at least a little bit guilty (note the pause she makes before asking "it was physics, wasn't it"), so she decided to revisit that library scene and offer actual help to Michiru.
