Missing Boyfriend Sticker Quest

[Lucifer Morningstar]

Indeed, it is I again in need of clarification. 

I've just finished Devon Corp and through Youtuber Dai Laughing have realized that I missed a sticker quest, the one involving a girl in the Pokemon center whose Boyfriend fell underground during the plant attack. 
Am I too late to complete it now?

The girl is still alone in the Pokemon center and still tells me that her boyfriend is missing but the boyfriend does not appear in the railnet. 
I tried it before and after talking to the girl and even tried both versions of the game, original and follower but still nothing. 

I haven't defeated Adrienn (or fought them for that matter) so the railnet hasn't been restored yet.

You should get it after restoring the railnet when you talk to her again. This is also the case for other stickers in Reborn city that you miss before the restoration, like the one with the girl from Jasper stuck because the elevator wasn't working. Since you're the one responsible for the city's restoration, they are still thankful for indirectly helping them and give you the sticker.

I'm pretty sure the Missing Boyfriend sticker is the only one I'm missing but then again until I discovered that one I didn't think I was missing any.
I know I got the elevator girl sticker. 

TY.
