It doesn’t matter if it’s something small like a box of candy or roses — the point is that you’re saying “please like me” rather than presenting yourself as the kind of high-value man who’s evaluating her as much as she’s evaluating you. You’re making things unnecessarily formal (and maybe even a little bit awkward) by bringing her a “romantic” gift.
Remember that you two are just getting to know each other at this point.
This means that a gesture like roses or candy can seem forced, awkward or even desperate.
You are always in two minds what to do and what not to.
Basically when you see something amazing that reminds you of her that isn’t that expensive.
Especially on a first date, bringing her a little something small that you spotted can go a long way. For example, if she confesses to you that she still watches her favorite cartoon from childhood, go ahead and grab her a Spongebob figurine if you see one in your travels.
All notes said things like 'You're beautiful', 'I'm so glad I met you', 'You're my everything' and things like that.
