Who's Texting Young-Ok in "Our Blues"? 3 Convincing Theories

Young-Ok opens up to Jeong-Jun about her last boyfriend before coming to Jeju two years ago. Named Choi Seong-Ju, the two met while working together at a handmade shoe factory in Cheongju. According to Young-Ok, Seong-Jun is a successful shoemaker whom Young-Ok assisted. While the exact details of their split haven't been revealed yet, Young-Ok implies it wasn't necessarily a clean break when she gets worked up talking about her ex's asinine excuse to break up with his previous partners in episode six. There's a possibility that Young-Ok launched into that rant because she's still upset over Seong-Jun's inability to leave her alone following their breakup.

Young-Ok met Cheol-Ung in Gangneung at age 22, whom she dated for two years. Cheol-Ung could sing and play the guitar well, but, to her dismay, he would transform into an unpredictably different person when drunk, as per Young-Ok's description of him. And while he never physically lost his cool with Young-Ok, or any other woman, for that matter, he'd get into violent altercations with other men when intoxicated. When he picked a fight with a passerby one day, Yeong-Ok herself reported him to the police and later broke things off with him, leaving Gangneung.

Based on the portrait she paints of her time with Cheol-Ung, it appears he'd still be hung up on her since it wasn't a mutual breakup. And the erratic texts and phone calls do seem to align with his volatile nature. After all, Young-Ok calls him a "total thug" when defining his character traits. Could it be him who relentlessly keeps attempting to get back together with Young-Ok every now and then? While Young-Ok seems bothered by any contact maintained by this unidentified person, her reasons for not fully cutting ties might come to the forefront as we head deep into their story with upcoming episodes. Moreover, episodes 13 and 14 are titled "Young-Ok, Jeong-Jun, and …," which suggests we'll delve into this mysterious character during those episodes.

Young-Ok isn't a Jeju native like Jeong-Jun. She moved here only a couple of years back, and despite having moved around a bunch of times, she seems content enough to say she might put down roots in Jeju. Whenever the subject of her family comes up, however, she dodges the question with different answers each time. She tells some her mother's an artist, while she tells others she has no parents at all.

There could be a sound reason behind her inclination to not disclose any actual information about her family members. Is she not on good terms with them? Did something monumental happen in the past to cause the distance? It stands to reason that someone from her family might be reaching out to her if they are, in fact, in the picture. Could it be her parents, or a sibling, perhaps? We'll likely get all the answers in future episodes.
