Let’s not throw the label home wrecker without much consideration. They are a home wrecker if they had intention to destroy the relationship.
I’d say at the current chapter it seems that the ex gave the advice with good intention. Not wanting another person to suffer as he did no matter his short his relationship with Han was should be a norm. it’s not like he told him to break up. It is up to Shinwoo to consider and act upon the advice. And why are people being choosy on who is giving the exact same advice.

I disagree. His advice was neither rude or had bad intention. He just warned him. You can see how sad the ex is. He doesn't want him back, he just remember one side messy relationship and he warns him about the ml's quick changing hearth. And ml has a history too. He spoke nothing but facts. And let's be honest everyone would want to be someone's "exceptional love" but it is really the case in real life. If someone's exes , friends and family warns you about habit of your loved one take it seriously. You can't see it at the start but usually it would be too late when you realize.

i get what you mean but i never called him a homewrecker, im saying that when you give unsolicited advice like that you can become one without realising it. if you received that advice from your current partner’s ex, you would definitely think twice about your partner no? its just a shame that this ex unknowingly put shinwoo into a worse state of mind about han, and the fact that this will likely be a major plot point in this series frustrates me. han has already realised what he did wrong in the past and is trying to reconcile with shinwoo for those actions so he doesnt ever feel abandoned again, now this ex’s potentially “good gesture” can become something worse. i dont think the ex is a bad person i just feel like he’s here to bring angst.
Not really hating the ex but hey real talk, even if it looks like he is looking after Shinwoo or out of concern, what they are what they will be is none of his business really so he shouldnt be giving any unsolicited advice. There are reasons why people are how they were and there are also reasons why people change so he shouldnt be giving advice based on how he knew him or how they were.
While granpa and ex both said Shinwoo should call the shots, the intention was different. Granpa adviced out of concern for Shinwoo that Han will control his life to not let him go(bec he knew Han is really serious about him), ex said that bec he thinks Han will leave him eventually bec he knew him to be not serious and fickle minded. More like badmouthing rather than being concern. Grandpa knows Han more, he is family and took care of him from he is young so he has the right to give that advice while ex duh they were just dating for a couple of months he was giving a piece of his mind like as him he knew him for like soo many years lol.
