... this was super cute until both said the other was their first love.
The girl is still adorable, but that they were already in love annoys me. Let's see what the backstory is.
If you were to somehow see that your friend left behind their phone, take a photo of it and send it to your friend's account. It is the best way to rub a salt to your friend's wound hahahahaha
I spotted two drawing errors with the phone. One had the camera block rotated 90 degrees, one was a mirror image. I bet the mangaka spotted them as well, when scanning through the finished manga, and it would bother her(?) a lot.
