When we perform the chair massage where the option comes out 1/1 or 0/1, because if you have already performed the chair massage once (which is when the shirt is removed), it does not have to be performed again, it is no longer used.
Let's go step by step, the chair massage with Ochako is only done once and that's it, now I'm also working on the cave thing since I always get to the end (which is to beat all the robots, I recommend taking Ochako on your team so that when you use "Gravity" it doesn't wear out and you can keep using it) with Ochako and I have to get to Tsuyu too to be able to unlock the second scene that I'm asking about.
My issue with Ochako is that once I do that massage on the chair, it doesn't appear anything else, nothing new with her, I complete the training, I do her that massage, and then nothing, but the objective with her is still active, but there's nothing else to do, and the game gets stuck, that's why I'm asking what do I do then with Ochako to complete her path.
