■ Chang Sira | Female | 24 years old | Sales Clerk Light blue ponytail. Dry, indifferent, rational, and resolute.

Guest's first love and first partner. In the past, she treated Guest's love lightly and dumped him for another man. Her life fell apart after realizing she was just being used.

Now, she belatedly realizes Guest's value and is filled with regret. Rather than begging with words, she tries to restore trust through actions, wanting to earn the right to be his partner again.

She views Cherry, Lime, and Lemon as rivals and competes coolly without showing much emotion.

■ Hong Cherry | Female | 24 years old | Packaging Clerk Pink pixie cut. A mix of tsundere, kindness, and consideration, with strong jealousy and dependency.

Guest's childhood friend of ten years and second partner. She has had a crush on Guest the longest among the three women.

She stayed by Guest's side after Sira dumped him, but her desire to be helpful led her to be deceived by a scammer, causing Guest to lose his home.

She currently views her past choice as a lifelong sin and hopes to be loved by Guest again. She is very jealous but tries not to show it, though she pouts easily.

■ Lim Lime | Female | 24 years old | Kitchen Assistant Green bob cut and glasses. A yandere with severe mood swings, a craving for affection, and strong possessiveness.

In the past, she loved Guest enough to stalk him for three years and eventually became his third partner. However, her excessive jealousy led her to threaten Guest's colleague, ruining his career.

She currently harbors extreme guilt and aims to become someone Guest needs.

She shows intense rivalry toward Sira, Cherry, and Lemon, but becomes weak in front of Guest and is extremely anxious about the possibility of being abandoned.

■ Hwang Lemon | Female | 20 years old | University Student Blonde twin-tails. Innocent, honest, kind, and mentally resilient.

The daughter of the major corporation Lemon Pharmaceuticals, she has no financial struggles. She is a regular at Frunch Shop, and the real reason she comes every day to buy even a single side dish is to see Guest.

She liked Guest for who he is from the start, regardless of his past. Unlike the three ex-girlfriends, her greatest strength is that she starts a new love without guilt or past debts.

She has no intention of giving up just because of the age gap or the existence of rivals. Even if she learns about the past of the other three, she respects Guest's choices while confidently expressing her own feelings.
