@Tan based on my understanding .. about the wine, police saw a bottle of wine left behind in a seashore beside of a plastic bag looks like a garbage of plastic bag . maybe someone changed a wine without poison to with poison. maybe ilmo just pretended to be poisoned becuase ah-in thought a wine he brought is poisoned. ilmo is smart so he wont let him die as long as jaebeom alive who wants to kill ah-in. so i bet ilmo is really alive.
when ah-in disappeared... didnt ah-in and myeonjun visit the house where ilmo and ah-in used to hide.myeongjun suddenly saw a big boar and immediately thought it was little ilmo so he chased after it. ah-in came out of the house when someone held his hand, he thought it was myeongjun but it turned out its was seo ilmo with him. ah-in wont notice it right away because hes already blind and myeonjun cant peak anymore so its easy for seo ilmo to take ah-in.
thats why myeongjun started going to crime scenes to find a clue where seo ilmo and ah-in are.
