Forgot a bl manhwa

Im pretty sure it's a yaoi bl manhwa. The mc is a brownhead guy and the ml is blonde. So when they were kids they got into a car crash and the blonde guy forgot his memories and they flew out of the country(?). Both of them kids were having taekwondo (?) classes. The plot i think is that the blonde guy didnt actually lost his memory, he swapped bodies with another guy. The mc met the blonde guy again he recognizes him. The blonde guy later then approaches the mc. The mc thought that the blonde guy recognizes him but instead... Yk what, im done explaining lololol. Im pretty sure it was common to be found on the mangago main page. ლ(´ڡ`ლ)
