So like mi-eum (our bottom) wanted to know about the past he had with Ji-tae (our top) and ji-tae would avoid telling him saying they had no past together whatsoever (cause he wanted to protect our boy) and this hajoon guy tricked mi-eum telling him he’ll tell him everything if he comes over to his club (cause he wants to destroy Ji-tae & his relationship) so instead of going to the airport like ji-tae told him mi-eum sneaked into the club and hajoon gave him some weird ass drink (maybe aphrodisiac) and started telling him how he has a name tag with “Hajoon” written on it and other stuff triggering his memory and at the same time ji-tae (our top) reaches there sees them together and hajoon again starts bitching about their past saying mi-eum is the reason for ji-tae’s miseries and eventually our boy mi-eum memories gets triggered then we got all those past chapters about them leading to today’s chapter of mi-eum finally remembering everything.
Mi-eum just knew ji-tae’s mom as a nice lady who he used to converse with since he was lonely (his dad also didn’t come home frequently) and didn’t had a mom and used to tell him all about Ji-Tae even though he only first met him after the murder of Ji-tae’s mom that he saw himself and felt guilty that he couldn’t prove that it was a murder and not a suicide. So he hung out with ji-tae in order to take care of him as a friend ( ji-tae’s mother told mi-eum it would be nice if he could be friends with him) and ji-tae knew all about the secrets mi-eum was keeping from (about not knowing his mother when he helped him out of goodwill when ji-tae fell on road after his mother death) then they had a fight when mi-eum tried to tell ji-tae about his past with his mother and they lost contact for some time then one day when he came home and saw ji-tae being tied up by his father. ( his father tried to kill ji-tae cause maybe he had a Debt history with the women who killed ji-tae’s mom and she told him to kill ji-tae??. We still don’t know what other reason he had to kill ji-tae…we’ll know eventually)

Can somebody PLEASE explain everything abt this to me like i dont remember/understand anything.
