I'm so lost and confused, the timeline feels so messed up.

A few of the ch.’s were flashback.
1. Chi was in love w/ his best friend. The blond guy w/ short hair and the mole; his name is shinoda hisashi. He looks like the current boyfriend Hina
2. The new manager w/ black hair is Ijima Hisashi, friend of the boss Shige. Chi ex sex friend
3. Chi and ijima used each other as substitues for the people they actually loved. They didn’t love each other.
4. Blonde hisashi came to visit chi, chi confessed and blonde hisashi told him he’d consider it. The next time chi saw black hisashi he was told him what happened w/ blonde hisashi and now i’m just speculating but i believe black hisashi was jealous that chi might actually get to be with the person he loved, while black hisashi still couldn’t be with shige.
5. I think black hisashi sent either pictures or videos of him and chi getting busy to the best friend blonde hisashi, and blonde hisashi changed his mind about considering being with chi and wound up getting married. Basically their friendship ended and any prospect of a relationship as well
6. Im not sure but it looked like black hisashi might’ve also beat chi as well. Chi is now worried w/ black hisashi being back that he’ll do something to mess up his relationship w/ Hina, long hair blonde and try to pick up where their twisted relationship left off.
I had to go back and forth a few times to figure out wth was going on as well
What's knotting? Why did hyesung feel so much hurt?
Dude you can literally type this into google. What are you doing?
knotting is when an alphas males penis enlarges to ensure the chance of a successful pregnancy and its apparently very painful as it makes it harder to remove the penis- many canine animals like wolves also undergo knotting when mating with their partner
