probably, what does it say on the third visit?
Yes, the date places and plan on wedding preference. Then the second one, information that Dr. Rose is going back again. After that, do not visit Daisy Shop again ❗❗ because this will trigger Dr. Rose to kill your char. Even though your (recent) favourite flower is (ur choice), at your death by Dr. Rose it'll said that when in childhood time, ur favourite flower is yellow rose. The first and second visit to Daisy shop is just to gain clues we need to solve the conspiracy (mobs, policy), it is a safe+important line.
About Dr. Rose being more active on killing they targets. Just don't visit third time, only first (brought Lawrence's missing posters) and the second (brought Lawrence's missing posters part.2(this is before Ralsei a.k.a Asriel and Chara will visit Black Swan. There's a chance you could die, just be careful with what will you choose.
