Notably, the same cat plush was said to have appeared in an Instagram photo in February last year posted by an acquaintance presumed to be affiliated with Im Su-bin's agency, drawing interest. Earlier, that acquaintance's Instagram uploaded a home-date video of Im Su-bin and Park Hee-sun watching ‘Single's Inferno 5’ together, which became a hot topic.

Amid such indications, online users continue to speculate that the two may actually be continuing to date.

Meanwhile, in the Netflix variety show ‘Single's Inferno 5’ behind-the-scenes program ‘Single's Inferno Reunion’, released on the 14th, Im Su-bin and Park Hee-sun offered candid answers about whether they are a real-life couple.

That day, Im Su-bin said, “We had about a month and a half before Hee-sun left for the United States, and we went on about five dates during that time” and “I remember having to suddenly go home during a date because of a curfew.”

Afterward, when Park Hee-sun returned to the United States, the two ended up living apart. Im Su-bin confided, “When I heard he was going to the United States, I wondered whether I should let go,” and Park Hee-sun honestly shared, “In the beginning, there were times when oppa did not respond for 2-3 days. I wondered whether he had no feelings.”

However, the two resumed staying in touch. Im Su-bin said, “Thinking that he would return in a few months, I changed my mind, and after that I reached out whenever I had time.” Park Hee-sun added, “As it went into the latter part, we made many more phone calls and contacted each other more often. I think we came to rely on each other.”

Park Hee-sun said, “It has not been long since I returned to Korea, so we still need to get to know each other better, but my feelings from then continue.” Im Su-bin also said, “Hee-sun said he turned Hell Island into Heaven Road, and after the broadcast I promised that I would turn it into a Heaven Road. I have not completely kept that yet, but I will keep it going from now on,” raising expectations for the future of their relationship.
