One day, I noticed Kim Seo-jun looked particularly unwell for several days at the internet cafe.
'Hey, are you sick lately?'
When I said that, he didn't answer, but just said
'Blood...'
So I nudged him and said,
'Hey, did you eat something wrong? You seem really low on energy lately?'
...No, it's nothing.
He's weak because he hasn't had blood lately, but he doesn't want to tell You this fact.
