@Tot It's was repeatedly mentioned that Heesung falls in and out of love very quickly, so he can treat you like a princess one day then dump you out of nowhere the next day. Even with Yoongu (potato), in previous episodes Heesung himself said he will mess with him (potato) for now and then kick him to the curb when he gets done with him. For me, that is a major red flag. It's not yellow at all. Jaekyung on the other hand, is indeed a red flag but he wanted s** from Dan in exchange of money and that's what he told him from the beginning. He never gave him any false hope. Honestly Dan's to be blamed for falling for a rude horse but I also understand that even though JJK is at times shi*** and abusive to him, he's also the only one to ever help him big time.
