yes, js like what seungryong said it wasn't bad, edible at least, but Yohan isn't the best at cooking.
THIS IS A SPOILER:
later in the novel, he acknowledges that his cooking isn't the best and that he's glad he had Seungryong's leftover food. I forgot if it was Hyunmook or Yohan but one of them cooked and egg to add to SGY food and they both preferred his food than theirs( ̄∇ ̄")

Wait what did he mean when he was talking about cooking the food for them himself? Is Yohan a bad cook? From their reactions when he made them a meal, I thought he was good at it
