※This article contains spoilers. Channel ATV Series "Marry Me" EP5 (viewership rating 0.9%) is about a man who hangs around Hana (Jo Soomin).
The identity of the unidentified person who was involved in the death of his former lover was revealed. Cheol-hee (Lee Yi-Kyung) had an unwashed sense of guilt for the death of his former lover. Hana said, "Even painful feelings need to have an expiration date.
The reason why Cheol-hee started living as a single man on the island was related to the death of his former lover, Da-bin.
However, on the day that Cheol-hee was dispatched to a fire scene and was unable to attend the meeting, Da-bin was involved in a traffic accident and died. Cheol-hee confessed all of this to Hana,
He thanked Cheol-hee for believing in him and telling him things that were difficult to say. The people who have helped heal Cheol-hee's wounds and given her strength to live are her twin niece and nephew, Bada (Ahn Tae-hee).
On her first date with Ina (Ji E Suu), Cheol Hee showed her affection and sense of responsibility for her nephews. Ina agreed to let Cheol Hee take care of her nephews.
Cheol-hee responded that she was able to live like a normal human thanks to the twins, and that the twins were the force that gave her life.
Seeing Cheol-hee like that, he was impressed by her kindness and positive attitude, but he couldn't easily respond to Cheol-hee's question about whether having twins was actually a burden.
Hana was filled with an ambiguous emotion that was not quite jealousy as she watched Cheol Hee and Ina's first date. Hana returned home after midnight.
When Chul-hee said that, he became angry and asked if Ina had any strategy, as she had decided to meet up again the day after their first date.
Meanwhile, the identity of the vehicular terrorist who had been threatening Hana is revealed: it was none other than Da Bin's younger brother, Jin Young.
Cheol Hee and Jin Young feel nostalgia, regret, and guilt towards Dabin.
The two, whose hearts were still in pain from the loss of their loved ones, wondered, "How can we live our lives remembering the sad past for thousands and thousands of years? How can we live our whole lives in pain?"
Hana's words, "It's not polite to leave you behind after your past love," helped me to ease a little of the burden I was carrying.
