@AKUTAGAWA WIFE from what i understood, after ah-in got blinded by the eye bags guy, he heard a loud gunshot and a body getting dragged into the water. it was implied that he thought the eye bags guy killed ilmo and later jumped into the water to ran away. but as it was later shown, it was the other way around - ilmo shot the eye bags guy and he got into his clothes so everybody believed that the real seo ilmo died and the eye bags guy ran away. one year later, ilmo returns for ah-in who is now really blind and can communicate with myeongjun only with the latter using text-to-speech (myeongjun got his tongue cut after the eye bag guy kidnapped ilmo and then released him). when myeongjun started chasing that boar, he left his phone and ilmo came out of hiding and took it, now pretending to be myeongjun, probably for ah-in not to reject him anymore.
