In Episode 7 of One Ordinary Day, Lawyer Shin Joong Han finds new suspects who could be linked to the chrysanthemum case. The suspect list includes Hong Guk Hwa’s friend, a drug supplier, stepfather, neighbor, and truck driver. It seems each of them hides a reason that could be the motive of the crime. However, the question remains’ unanswered, is the killer really among them? Well, One Ordinary Day ending has given explanations about it. Let’s go through all suspects one by one!

Yoon Hyo Jung (Friend)

Yoon Hyo Jung was the late Hong Guk Hwa’s friend and the first suspect of this murder mystery. It reveals that a week before Guk Hwa’s murder, she and Yoon Hyo Jung had fought very badly to the point Hyo Jung’s injuries required three weeks of treatment. Episode 7 also reveals the reason for their fight. Yoon Hyo Jung had found about Guk Hwa and her boyfriend Uhm Ki Jong’s sexual intercourse. Therefore, the girls had fought, and eventually, Hyo Jung moved out of Guk Hwa’s house. On the night of her death, the two were supposed to meet. However, Guk Hwa did not even answer her calls or messages.

Uhm Ki Jong (Drug Supplier)

Ukm Ki Jong is the second suspect who appears on the witness stand. Shin Joong Han discloses that he and Guk Hwa had sexual intercourse, and thus that had led to the rift between his and Hyo Jung’s relationship. Ki Jong also admits the same. Although they had slept once and he was Guk Hwa’s drug supplier, nothing fishy stands out that would point towards him.

Lee Chul Ho (Truck Driver)

One Ordinary Day ending exposes the third suspect, which we’re all doubting from the beginning, the truck driver Lee Chul Ho! It shows that Lee Chul Ho had once delivered a package at Guk Hwa’s address, but she had filed a complaint against him. After all, receiving negative reviews in the delivery industry is not a good sign. Coincidently, he saw Guk Hwa that night at a gas station and followed her and Hyun Soo to Han River.

Since Lee Chul Ho is an ex-convict, he wears an ankle monitor. However, his ankle monitor was turned off for an hour that night. Therefore, when Shin Joong Han questions this, he scornfully answers that the ankle monitor’s battery was dead.

But soon after Guk Hwa’s death, Jo Gang Pil obtained her insurance money and put her five million dollar house on the market. Even though he has the motive, Prosecutor Ahn proves his alibi. It shows that night, her stepfather was at a motel with his girlfriend.

Initially, Shin Joong Han reveals Yoo Seung Hun’s weird habit of parking his car in front of Guk Hwa’s house, which is 1km away from his own. The second disclosure shocks everyone that Seung Hun was stalking Guk Hwa for the past few days before her death.
