The supporting character's harem is very normal - Chapter 503: This Male Lead Is Too MiserableLaleth Garden.

“Ah, him? He’s just Daeyeong’s acquaintance.” He hated those words. Choi Seolwoo is trying to leave behind his teens and twenties, which he spent as Won Daeyeong’s shadow. Won Daeyeong (gong), the national team captain who became the first Korean track and field athlete to qualify for the Olympics in the 400m, and Choi Seolwoo (soo), a newly qualified Certified Public Accountant, are childhood friends of over a decade. Choi Seolwoo, weary of the pain of his obsessive unrequited love for Won Daeyeong, impulsively enters into a contractual relationship with a sub-seme and declares a break-up with Won Daeyeong, intending to completely remove him from his life and start anew. Won Daeyeong is displeased with Choi Seolwoo trying to end their friendship over a relationship. Just how much attention had he demanded since they were young? Even he himself acknowledged how incredibly well he’d treated him. It wasn’t as if he had expected anything in return for looking after him, but still, this is absurd. To take him for granted and push him aside like this. Won Daeyeong proposes that if Choi Seolwoo appears on five episodes of a segment called “An Acquaintance” on his Xtube channel, which has 1.1 million subscribers, he will agree to the break-up. The filming of a variety show exposing every detail of Won Daeyeong’s life begins. Unexpectedly, the view count explodes due to the spicy and entertaining talk with frequent bleeps, the genuine bromance chemistry and realistically fierce fights, and Choi Seolwoo’s idol-like visuals. Choi Seolwoo, the “break-up guy,” ends up advertising himself to the entire nation as Won Daeyeong’s best friend. Wait, somehow this… seems to be moving further away from a break-up…?

Ye Beibei was unprepared for a while, and she married Young Master Gu who was sitting in a wheelchair.

I thought that from then on, I would have lived a career as a wealthy man, rich and free, but I never knew I was enslaved every day to become a nanny.

Ye Beibei beat the table: Liar, I want a divorce!

Young Master Gu pushed a cute baby to his front: You still want to get a divorce even when we already have a child? Wife, you wake up!

“…” Ye Beibei looked at a cute baby, who was exactly like her, with a confused expression.

Who can tell her when she gave birth! ?
