This is not canon for Jeaki but it's just a thought. Okay, so y'all remember that Jeaki was, in fact, originally not Jumin's. In some chapters, he is but mostly he's not. So since I ship Jaehee with both Jumin and Zen. What if Zen was the black out drunken baby daddy? Nobody knows because maybe Jeaki took more of Jaehee's features when he was smaller but then he grows and its like "Wait, shit! He looks A LOT like Zen. IS HE ZEN'S?!?" And then Zen's like "Ive been his metaphorical uncle this whole time and now I'm his father?!" And Jeaki is like "I guess it doesn't matter now since I'm more grown and have had this dude as my dad for my whole life so now I have two dad's and one mom," and then Areum is questioning like "am...Am I really the product of you two?"

Lol it's late and I just thought for a moment which is never good. This might happen in SOME future chapters if I need to mention who exactly Jeaki's real father is but other times it MIGHT not be Zen, idk what I'm gonna do. I can't tell the future.

Peace! Why am I like this?
