Many are already saying or thinking that Takamada will hurt Yu like in the first episodes. First of all, Yu trusts her boyfriend a lot, and there is consent compared to the first episodes. Also, we were given hints that Yu does have a masochistic side and that she accepts everything that feels good.
know Takamada won't harm Yu to the point of affecting him psychologically. Besides, we're talking about Yu, the most masculine, mentally strong, and resilient character in this manga. I’m sure that once Takamada has let off some steam, they'll talk it over and come to an agreement to avoid hurting each other and to ensure they both enjoy it. I trust them.
