It was nice that CJH made the time to attend PEB's concert. I think it would be more suspicious if she didn't announce his attendance and that he showed up secretly. PEB invited the whole Castaway Diva cast to attend her concert and CJH would have come if he were in Korea so his attendance in Japan was not a shocker. Her concert is an extension of her Mokha character and I believe it will be included in the blu-ray. She announced his presence as Kiho and not as CJH. Either way, it was nice that the whole cast was able to attend to support PEB.
My strong shipping of PEB and KSW has waned after over two years of not many crumbs so now I can actually see things more objectively. There are two things about PEB that I find a bit odd and surreal. One, PEB is a 31yo woman, it's hard to believe that she never dated. Even if she prioritizes her career over her love life, there's no way that she has never been in love or at least been attracted to someone. A heart has a mind of its own and it wants what it wants.
Two, it's strange that besides KSW, her other MLs don't post couple photos on their ig. CJH posted couple photos of his FL from Love All Play and KTO posted a picture of him hugging Ha Yoon-Kyung (aka Sunshine) before he deleted all his posts. They all find PEB to be kind and easy to get along so why don't they post couple photos with her? This brings me to KSW. He's the only ML to feel comfortable enough to post not one but many photos of just the two of them and he even sent her a CT. I admire his bravery and if they ever get to cast together again, it will be a HUGE hit!
Side note, of all her drama BTS, I find PEB to be the most playful, giddy, and happy in TKA. KSW is still her best partner. She has yet to describe any other MLs as handsome or best partner...
