1. Are the dating rumors between Ji Soo and Seo Kang-joon true? Suspicions of 'lovestagrams' and 3 clues

The hottest topic in the community these days is definitely the dating rumors between Blackpink's Jisoo and actor Seo Kang-joon! It all started with an analysis of their movements and social media posts uploaded by an overseas user X (formerly Twitter). The two had previously showcased legendary visual chemistry as virtual dating partners in the Netflix original series *Monthly Boyfriend*.

 

There are three main clues regarding the "lovestagram" and dating circumstances raised by fans.

Profile picture with a similar vibe: The reaction is that the overall composition and tone are similar, giving it a couple profile vibe.

Stay in New York around the same time: The point is that Instagram photos taken in New York during the overlapping period were uploaded with a slight time difference.

Coupling Allegations & Concert Visit: In addition to the similar-looking ring designs, there was a report that Seo Kang-joon, who is known as a homebody, visited the Blackpink concert venue on a summer day.

 

However, there are absolutely no sightings of actual dates or official photos, and since neither side's agency has officially confirmed it, for now, it is closer to a fan-driven speculation!

2. The Full Story of the "Trash Controversy" and Remarks by Lee Chang-sub During a Web Variety Show Appearance

A controversy arose regarding the level of expression due to aggressive language and behavior in a web variety show featuring BTOB's Lee Chang-sub.

 

The crux of the story was "a relationship conflict that arose because the boyfriend, who picks her up in his car for every date, asked her to throw away the trash in the car." Lee Chang-sub deeply sympathized with the boyfriend's position and used a series of heated and somewhat harsh expressions, such as "terrible manners" and "no consideration whatsoever."

 

In response, some viewers pointed out that even though it is an entertainment show, the attitude of excessively criticizing the other person was uncomfortable to watch.

As the controversy grew, Lee Chang-sub left a sincere apology through a fan communication platform. He honestly reflected on his words and actions, stating, "I had become desensitized to stimulating things due to the pressure to be more fun and memorable," and conveyed his intention to return to his original mindset.
