Ti crees que Poppy recolectaba pósters de Branch antes de que se volvieran novios
Translation: "Do you think Poppy collected posters of Branch before they became a couple?"
Wow, it's been a while since there's been a question in Spanish. :D But to answer, not exactly, but more or less.
I imagine you're asking about Branch Jewels (from the Older Sister AU), since Branch Puffer (Younger Sister AU) was kind of cryptic when it came to taking pictures. There aren't many of him, and the few that exist he guards jealously.
But no, since Branch Jewels and Poppy (Gyaru) became a couple when they were teenagers, and back then Branch hadn't yet joined the PMF (you need to be at least 18 to enlist), so that kind of publicity like this drawing couldn't have been done back then, and not before either, because Branch was just recovering from his teenage awkwardness, and he didn't really like being the center of attention.
However, even though he didn't collect posters, Poppy definitely collected pictures of him. Of all ages. She was always looking for an excuse to ask Berry for a copy of a photo or to take pictures with him of special moments, even before they were dating, which is why she now has a bulletin board with pictures of Branch in her room. She also has a special little photo album that she titled "My Boyfriend Bwanchy♥" (≧▽≦)
Although it's also likely that Poppy herself made her own posters of Branch at some point using photographs. As I mentioned in a post, Gyaru Poppy is a stationery fanatic and has a little bit of everything, so she probably managed to turn a photo of Branch into a poster and use it to decorate her room.
