A post shared by Pia Wurtzbach (@piawurtzbach) on Jun 9, 2018 at 5:13am PDT

It was only a few weeks ago when they shared that a simple sorry is enough to fix most of their misunderstandings.

Well, it appears one of them needs to do some apologizing anew after it was found out that Pia Wurtzbach and Marlon Stockinger unfollowed each other on Instagram again.

They were seen in public for an event together just two Fridays ago, but by last weekend they were no longer online friends.

This had fans worried about the couple's relationship, which was thought to have moved past a rough patch after they talked about how happy they were in an interview back in June 20.

"We laugh a lot. We have so much fun palagi kami tumatawa palagi kami nagbibiruan," shared Wurtzbach as he spoke with ABS-CBN News' Jeff Fernando in a joint interview with Stockinger.

The couple did reject questions about marriage, but Stockinger said that he continues to enjoy learning things about his girlfriend, even after being together for more than a year and a half.

It was in July 2017 when Wurtzbach and Stockinger first unfollowed one another for still unknown reasons.

Some gossipy netizens linked the new incident with Wurtzbach's decision to watch the concert of South Korean boy group Super Junior last Saturday, where she was seen fangirling over member Siwon Choi. She even posted a photo with the star on Instagram.

Other fans defended Wurtzbach, however, and begged to leave out Siwon from the controversy involving her and Stockinger.

If you dont want local news portal to drag siwon into whatever pia×marlon has, you need to stop dragging siwon into pia as well. These sites will pick up whatever makeup stories they can as long as it can gather likes. They gonna drag whoever.

Stop dragging Siwon in the issue between Pia and Marlon. Miss Pia only attended SS7 because she's a fan. Siwon acknowledged her presence because she is a renowned person who got to attend the con.

I hope people will stop dragging Siwon into Pia and Marlon's love affair - if the couple has broken up or if they are currently okay or not okay -- it is srsly not okay to drag Siwon, to blame Siwon or whatever. I just hope we could give the 3 of them respect.

Pia & Marlon are at the right age to make decisions for themselves on who they decide to date. Siwon is not involved in the IG unfollowing drama so he shouldn’t be mentioned in that article
