He demands to know why Byung-hoon returned to Korea after his friend died—guilt? Byung-hoon catches on that he knew Do-il pretty well. He wants an answer to his question—why did he take over the theater from his dead friend? Hae-shim answers that her feelings just poofed when he confessed, and chalks it up to a latent femme fatale propensity. Min-young asks about the strained air between Byung-hoon and Seung-pyo. Rather than address that, he turns it around on her and notes that she was equally awkward.
Rather than address that, she mumbles an excuse about just being surprised to see Master there. Grandma just wants them to fix it—they got Chul-soo onboard, so they can get Hae-shim too. Then she beckons Byung-hoon near and grabs onto his hair, shaking him furiously and insisting that he take responsibility.
Byung-hoon senses that something else is bothering Hae-shim, and tests out his suspicion by approaching her as a friendly visitor with extra coffees to hand around. He spills some on her wrist and dabs at it apologetically, which allows him to glimpse the monster bruise on her arm.
Are we back to the long-lost brothers theory? He instructs them to gather all the info they can on her past. That turns up a recent record of chemotherapy, due to a recurrence of her previously treated cancer. She has very low survival prognosis, and this makes Min-young insistent that they hurry to make the most of her remaining time.
Byung-hoon points out that they have the problem of Chul-soo being left behind, but the others all argue that it would be better to let the couple have their time. She chides Hae-shim for pushing Chul-soo away anyway, since she should live her life to the fullest while she has it—we all die in the end anyway.
Byung-hoon tells Grandma of his decision to drop the case. Grandma chides that everyone thinks of people with terminal illness as those already dead, just waiting to head on to the afterlife. But no, the sick are just like everybody else, wondering what to eat or do or see today: Seung-pyo happens to drive by to spot her, and takes mental note of the visit. On the way out, Yi-seol asks outright if she likes him.
Grandma takes the matchmaking into her own hands, and puts in a frantic call to Chul-soo pleading for help from the strange people who are trying to take her away. Chul-soo races to the hospital, and finds Grandma sitting down for a nice chat with Hae-shim. Grandma sits them down with a stern word to both: Chul-soo should buck up and give it a proper try instead of taking his first rejection, and Hae-shim should be honest about how she feels.
Then she moves aside to give them some privacy… only to bark at them from one table over to get going already. Moo-jin arrives at the hospital with Hye-ri today, and asks if she wants to wait outside. Just then, Grandma grabs Hae-shim by the hair and starts hurling curses at her, in another of her spells.
The news shocks Chul-soo, who returns to work in a daze. Playing dumb admittedly not difficult for them , they ask what the structure is for and insist she demonstrate, then lock her inside the box office with the newly attached latch. They leave her inside while chortling to each other, then head inside the restaurant to wonder loudly what disturbance is going on at the box office with Min-young. So Seung-pyo heads out curiously to find her asking for help, and agrees to let her out.
At the last second, he pauses to ask her to answer a question first: I guess he has his answer. Seung-pyo asks her to come by again, and to forget he every said anything so they can be like they used to be. He uses his wish now, which is for her to drop by the restaurant like she used to. With that, he lets her out. Min-young spots Moo-jin arriving outside with Hye-ri, and that makes her smile. He wants to continue with the case. Chul-soo goes out drinking with his firefighter buddies, and as he pulls out his wallet, he sees a scrap of paper.
So he calls Min-young, AW, to convey the message that Byung-hoon asked him to pass along: She returns to the team meeting more determined than ever, and the three of them pester him into agreeing. The operation centers around the next fire drill, which starts with Arang asking Chul-soo to help with someone who collapsed. Meanwhile, a separate announcement blares down below about Kim Chul-soo being injured on the roof, and he grumbles at the wrong report.
He says stiffly that it would just be the person closest in vicinity, but Min-young says she thinks it would be the person who cares the most. Chul-soo says he had thought the same way, and avoided situations to spare them hurt. He promises to stay with her till the end, then corrects himself: She asks the same question she did the last time: On the drive back, Min-young is in chipper spirits, and Byung-hoon teases her about her useless chatter at the restaurant.
All she can recall is him mentioning a hyung he can no longer see, which made him sad. I think I must like you.
