Based on their time together so far, Ruka Sarashina, not Mizuhara, might actually be the perfect girlfriend for Kazuya.
Kodoani.com – The following has spoilers for Season 2, Episode 4 of Rent-a-Girlfriend.
In Rent-a-Girlfriend, Kazuya has expressed his love for Mizuhara several times throughout the series. However, this can be simply infatuation or the paradox of first love, where someone gets a real taste of romantic love and becomes obsessed with it. More recently, based on their interactions with each other, Ruka Sarashina may actually be a better romantic partner for Kazuya Kinoshita than Mizuhara for a variety of reasons.
Mizuhara and Kazuya haven’t accurately portrayed the couple’s romantic reactions in the series so far. It seems very one-sided, only really highlighted when Mizuhara is helping Kazuya or Kazuya is helping Mizuhara, there hasn’t been a single moment when both Kazuya and Mizuhara are naturally compatible and in love. By comparison, the most recent episode of Rent-a-Girlfriend shows how emotionally balanced Ruka and Kazuya are when together.
Putting aside Kazuya’s love for Mizuhara, if Kazuya decided to be the real Ruka’s boyfriend, rather than just a test, they would be great as a couple due to their natural chemistry. Kazuya can be completely himself with Ruka. While Ruka is non-judgmental and can handle the real personality, Kazuya’s flaws. The comparison is seen when Mizuhara walks into Kazuya’s room and immediately shows how messy it is, while Ruka walks in, and doesn’t really care, she’s mostly concerned with Kazuya himself. .
Their reactions together are beautiful, as seen by many of their funny moments together. Unlike when Kazuya was with Mizuhara, both Kazuya and Mizuhara were restrained and hesitant about what they really wanted to express. While both Kazuya and Ruka are completely open and unattached to each other. Their playful moments are hilarious, as they joke around with each other when Kazuya tells Ruka to keep quiet, and Ruka playfully screams to tease him.
The two of them were perfectly comfortable doing mundane things together, acting completely natural. The two are seen eating together, watching something on a laptop together, and Kazuya casually asks Ruka who she’s texting or what she’s doing on her phone. Ruka did things like casually showering at Kazuya’s place, understanding that Kazuya most likely did it himself in the shower but didn’t really care or make a big deal out of it.
Ruka was more prepared for intimacy with Kazuya, they seemed less awkward when Kazuya and Mizuhara got intimate. Kazuya even fully confesses his sincere feelings about her, how she makes him happy and that she fully cherishes her with all his heart. Before Ruka left her apartment for the first time, she even walked in and kissed Kazuya on the cheek. At this point, unless both Mizuhara and Kazuya can be completely themselves together, not holding back anything like their romantic feelings for each other, Ruka is clearly the winner when it comes to being human. Romantic mate match Kazuya Kinoshita.
