bl manga name ?

the manga was bl & completed i’m pretty sure, but i don’t remember whether it was shounen ai or yaoi ㅠㅠ

the two were online friends & when they were meeting, the seme (?) texted him that he was holding a rose. the uke (?) ( who i think was blond ) thought that the other was a girl so he was imagining what they must look like since he i think knew that the other had black hair.
& i think one of them was wearing a striped shirt, but that’s not important-

( and i’m writing this here since it won’t let me write / ask this elsewhere )
