@PastaSouce My guess is that Seo actually found out that ah-in wasn't blind the first time that he met him. When Seo said he was going to get something else to use and poured wine on his di** ah-in messed up by yet again telling him that he didn't want to drink. Seo never mentioned what he was going to use so the only way that ah-in would be able to say this is if he saw the bottle, thus making him not blind. This chpater is just ah-in realizing that Seo knows he's not blind but my guess is that Seo's known for a while.
