By now, Episode 14, a lot of people have been complaining about how this 4th season of Heart Signal Korea is super disappointing. And that's true.

This is due to the casting/recruiting/etc. decisions made by the producers.

The 6th season of Heart Signal China has disappointing visuals but before that, this 4th season of Heart Signal Korea barely managed to triumph over Heart Signal Japan's lacking visuals.

First off, Mingyu, Hushin, and maybe Jiwon did not have corresponding female visual counterparts.

Second, of all the guys that Jimin (possibly the only female visual in the show) had to be interested in, how come it was the one that she couldn't even regularly meet (too busy with his career).

Third, although Heart Signal is not known for great fifth/sixth members or newcomers, after 3 years of break/hiatus, why didn't they just cast Kihoon's friend (Jiyeon/오지연 from Episode 7) from the Heart Signal Korea spinoff called Friends. She would've been the perfect counterpart to Jiyoung, they both have the same cute vibe but probably would've been totally different when it came to personality/et cetera. And so the events in the show would've been not as predictable (even if the end game couples and events also didn't leak beforehand).

Why focus on the visuals? Because clearly somehow people like Jiyoung's face despite her heavy plastic surgery and overdone aegyo and so the outcome of the show would've been varied instead of the same identical scenes over and over again.

If Jiyoung had a more mature/less cute/etc. counterpart, she would've been an interest still to some, but since Jimin was too busy chasing a specific person that also wouldn't reciprocate, it was decidedly in Jiyoung's favor.

Or again, if Jiyeon from Episode 7/etc. of Friends was cast for this 4th Heart Signal Korea season, then it would've been possibly not the same situations repeated ad nauseam.

On the other hand, Mingyu is basically the opposite of Jiyoung, as in he had everyone's interest save for Jimin (which still makes no sense since he interacted with her a lot, at her university, et cetera, but maybe Jimin has a specific type or something). And so if they got somebody that was more proactive or had dissimilar appeal than Hushin or Jiwon, then that person might've been able to change minds too.

I've seen all of the Heart Signal versions and basically all of these East Asian dating shows, and even though I like the non-romantic/etc. aspects of this 4th season of Heart Signal Korea, it is obviously maybe the most disappointing season yet.
