Look at the actual question. Chapter 21.5 Question: Is Taegu seoin’s RIVAL? Author’s answer: He is. That’s the part you missed. You only read the part where it says he’s an important character, but the meaning of being a rival to a male lead/love interest = another love rival. If it didn’t mean love rival, then they could’ve said he was an enemy, etc.
i think there’s no romance between my baby and old man taegu taegu just takes care of him
