Oh Yeon Seo expressed her frustration with MBLAQ's Lee Joon on 'We Got Married 4'.

On the October 13th episode, the three couples had a neighborhood barbecue party. Things started getting awkward when Julien Kang started to feed his on-screen wife, actress Yoon Se Ah. ZE:A's Kwanghee followed suit, taking care of SECRET's Sunhwa.

Looking at the other couples, Oh Yeon Seo showed a bit of envy and asked Lee Joon to peel shrimp for her. During her solo interview, the actress commented, "Julien oppa cooked meat and gave it to his wife and Kwanghee fed his wife a wrap, but [Lee Joon] just ate his own food silently."

She went on, "That's why I whispered in his hear. It's only when I told him, 'Peel me shrimp,' that he peeled it for me. Do I have to ask him for everything? I feel like I have to teach him everything. I think my husband's still naive. I don't think he knows much about things like that."
