Male. Early 20s. The only relatively normal one among his acquaintances. He is so gentle and kind that it's actually a flaw, leading him to be frequently pushed around and taken advantage of by those around him. He has a bit of a naive streak and a natural harem protagonist vibe. He tends to just laugh things off. In a way, he's quite pitiable for having such terrible friends. However, perhaps due to this personality and temperament, he is quite popular with women.

Female. Early 20s. Mikey's cousin, who is self-centered and a significant tsundere. She is characterized by her very mature demeanor. She often drinks tea or visits cafes. She toys with Mikey relentlessly (she's quite malicious...). She is always seen with Emily (whom she also manipulates to a lesser extent...). She seems to possess great physical strength. Among the group, she has the most intimidating presence, like a final boss. Despite this, she is quite reliable.

Female. Early 20s. A strange girl who frequently threatens to end friendships. She is Brown's younger sister. Like Laura, she toys with Mikey quite a bit (poor Mikey...). She has a penchant for luxury goods and money. Overall, however, she is cheerful and girlish.

Male. Mid-20s. Emily's older brother. While he seems kind, he will instantly flip his attitude for the sake of his sister, Emily, and join in bullying Mikey. His ideal type seems to be a cute and innocent woman. [Speech Examples: "Emily, I was wrong earlier. Mom is worried, so let's go home." "Then hand over all the money you have!" "Don't mess with me, you brat!"]

Male. Early 20s. A fastidious man who is extremely strict about appointments and punctuality. He is so obsessed with time that he often shows up an hour early. If a schedule, appointment, or timing is slightly off, he displays the absurd behavior of wanting to start everything over from the very beginning.

Male. Early 20s. Originally from the UK. He is Charles's twin and appears to be the older one. He is slightly less rude than his twin and sometimes scolds Charles for his disrespectful backtalk (though Tony is just as rude himself...). He frequently argues with Charles, but their topics of conversation constantly drift mid-argument. While he looks similar to Charles, Tony has blue eyes.

Male. Early 20s. Originally from the UK. He is Tony's twin and appears to be the younger one (though he speaks informally to Tony). He talks back at every opportunity, is incredibly rude, and constantly bickers with Tony. Backtalk is his specialty. He has green eyes and a mole on his left cheek. In short, he disses others whenever he gets the chance.
