The following contains spoilers for Season 2, Episode 2 of Rent-a-Girlfriend, "The Usual Girlfriend," now streaming on Crunchyroll.

Ichinose "Mizuhara" Chizuru starts to feel guilty about Kazuya Kinoshita renting her out every week. She expresses that she doesn't think it's right, as she understands that Kazuya is renting her out to support her financially with her dreams of becoming a famous actress, and not for her girlfriend experience services.

This may be because of many reasons. Mizuhara may be developing strong romantic feelings for Kazuya, which she doesn't feel right about due to them being a professional-client relationship. She may feel guilty that Kazuya is falling in love with her, and as a result, after Mizuhara quits, this may leave Kazuya feeling heartbroken. Mizuhara may also be feeling guilty, possibly knowing that Kazuya is in love with her, and is using his love to earn money.

This is the implication of many long-term professional-client relationships. Professional therapy services for example often have a limited amount of sessions for clients to prevent complicated feelings from developing. The resulting feelings may also cause a client to feel worse, and later have to find another therapist just to get over the complicated attachment felt towards the therapist, or the love not being reciprocated.

This is the problem with the Kazuya and Mizuhara relationship. They're still in a professional-client relationship in the series, and this can have serious consequences if romantic developments happen. For instance, if Kazuya does become Mizuhara's boyfriend, this could ruin her potential career opportunities due to her dating a client when she's supposed to be a professional. In the acting industry, controversial news is huge. Developing a relationship with Kazuya could ruin her reputation for good.

It's also not fair to Mizuhara if she has feelings for Kazuya. As a professional, while on their girlfriend experience dates, she won't be able to authentically express her feelings to Kazuya. Kazuya may think she's simply acting as a girlfriend. For both Mizuhara and Kazuya, it's confusing. There's a constant feeling of "what should I be doing," "how should I be acting," or "is what I'm doing acceptable," going through their minds.

As Kazuya realizes that he's not Mizuhara's boyfriend, he also realizes that things can't go on like this. In order for romantic developments to really develop further, either Mizuhara needs to quit her rent-a-girlfriend services as soon as possible or Kazuya Kinoshita needs to ask her to be her actual girlfriend and go out with her. The same way Mizuhara asked Kazuya out to go on the recent baseball date. As seen many times throughout the series, Kazuya and Mizuhara have great chemistry as a couple. The one implication to get through is the fact that they are constantly in a professional-client relationship.
