[1][2] The group's last formation consisted of members Doyeon, Changjae, Tey, Sanghyun and Jaemin.

In addition to photos of the members, the teaser announced that Mr.Mr will pre-release its title song on July 5 followed by first mini-album release on the 8th.

A music video teaser for Hon was released on their official YouTube account revealing that the group will be making a comeback with their 3rd digital single on November 8, 2013.

On June 17, it was confirmed that member Changjae would be starring the idol-turned-actors drama High School: Love On alongside Infinite members Nam Woo-hyun and Sungyeol with child actress Kim Sae-ron.

He has taken to Twitter to address certain complaints including his unfair treatment, physical and verbal abuse which he had received while still being in the group.

[3] Since then, both parties have been exchanging responses and Ryu has officially filed a lawsuit against his agency's CEO.

Following the controversy of Ryu‘s leave from the group, MR.MR announced their comeback plans for April with two new members join them, Sanghyun and Jaemin.

[5] On September 4, 2017, it was announced that MR.MR would be taking part in idol reboot show The Unit, a competition series on KBS that "aims to shine a spotlight on artists who have already debuted but failed to find mainstream success".

[6] On "Showterview with Jessie" it was confirmed by member Doyeon that Mr.Mr had disbanded and he was currently working as a manager for Hong Seok-cheon.

[7] It was reported that a transgender woman, A, had written a Facebook post maligning male idol, B, for casting her aside after taking advantage of her resources.

One of these guesses included Mr.Mr's Hon, which led the group's agency Winning Insight to release their official stance on February 17.

Contrary to A's assertions, the claims they were more than friends, they were living together, she introduced him to a host bar for work, and she filmed their sexual intercourse are all false.

Resulting from the controversial writing, Hon is having a hard time because of the shock and hurt he received from a friend whom he had trusted.

However, while Hon was preparing to debut as a singer, he had stopped contacting her, which made her sad and resulted in her writing these untrue claims after having a few drinks.

Due to this Hon left the group after this controversy, he wrote "I'm sorry because I think I worried and disappointed a lot of people.

But I wanted to say for certain that things in the post such as that I worked at a host bar, had financial troubles, had a video, and dated A are not true."

He added, "After A wrote the post drunk, she checked it again a few hours later and said that she thought she made a mistake.

Regarding this connection to Girls' Generation, a rep of Mr.Mr told that Asia Economy that the rumours were true.

/ Girl, you come out so easily from behind the curtain / Not me, but another mistake, Mr.Mr / I bet you're amused by my embarrassment," and, "I become faint for a main like you / Am I loser and are you a winner?
