The hit trend drama series, tvN's "It's Okay To Not be Okay," has shared new stills from the drama.

Spoiler alert!

The last episode set the netizens and the internet ablaze as Kim Soo Hyun gave a steamy birthday kiss to Seo Ye Ji. It was the second and most-awaited kiss for the viewers!

Aside from the unforgettable kiss, Sang Tae (Oh Jung Se) took the time to treat his brother Gang Tae (Kim Soo Hyun) for a delicious meal. He also gave his younger brother money for his allowance.

In her desperate move to get closer with Sang Tae, Ko Mun Young (Seo Ye Ji) tried to tag along and met the two brothers at the restaurant. It was a happy day for them as Sang Tae approved and befriended her.

Even if Gang Tae wishes that all of them may have a happy ending and nothing will trouble them again, he found a mysterious letter that gives him suspicions about Park Ok Ran's intentions (patient in the hospital). Ok Ran escaped the psychiatric hospital and visited the castle, pretending to be Mun Young's mother.

During the counseling session of Sang Tae and Dr. Oh, Gang Tae was there to hear for the first time about the mystery killer responsible for their mother's death. Gang Tae later found out that the person connected to his mother's murder is Mun Young's mom.

Meanwhile, Mun Young planned to have a so-called family portrait for the three of them, but the frustrated Gang Tae tried to avoid Mun Young, so he stayed in his room while the two went to the studio.

Mun Young tried to keep the mood afloat and helped Sang Tae choose his best smile. They settled at the center when suddenly, Gang Tae appeared in the room looking dashing in his black suit and waxed, brushed up hair.

Mun Young and Sang Tae smiled in happiness as the family portrait shot went well.

Viewers were in awe seeing Kim Soo Hyun with his neat, new look and formal attire. Seo Ye Ji also looked pretty in her white, close-neck dress. Oh Jung Se also looked charming in his striped neutral color suit with his signature adorable smile.
