Rentarou is so excited that he finally has a girlfriend that he talks about it to a telephone pole. Hakari and Karane show up, and the trio walk to school hand-in-hand while talking about the weather. Along the way, they start calling one another by their first names with and without honorifics. When they get to school, the vice principal chases down a student running in the halls and gives him a deep kiss. While explaining her reputation to Rentarou, Hakari and Karane discover that he's never kissed a girl before, which means whoever kisses him first will get Rentarou's First Kiss.
The group gathers on the roof during lunch, and Hakari and Karane take turns feeding Rentarou with bites from their bento and homemade cookies respectively. Hakari plays the bocky game with Rentarou, prompting Karane to try and play as well. Things escalate quickly as a wayward sneeze leads the girls to pretend he's sick as an excuse to kiss him. Rentarou catches on that they're both trying to get his First Kiss and, after calming the girls, explain that he created a game that would allow him to kiss both girls without anyone knowing who was kissed first. The game involves blindfolds, music through earbuds, and dice rolls, in order to randomize the order in which the girls were kissed. Hakari is immediately sold on the idea, but Karane points out that Rentarou could easily cheat without the girls' knowledge. As such, Rentarou implements a "failsafe" by having all three of them Pinky Swear not to cheat.
It doesn't take long for the game to spiral out of control, however, as the players repeatedly suffer embarrassing screwups. Eventually, all three of them decide the game is more trouble than it's worth, and Rentarou decides the sanest option would be to invoke the wrath of the vice principal. But when he leaves and the vice principal catches him, the girls wrestle and scare her away, explaining that he should let the other girl kiss him first instead. But that still leaves them back at square one, so Rentarou proposes a three-way kiss. (It was actually his first idea, but he rejected it since it would mean the girls would kiss each other in the process.) Having suffered enough embarrassment from the convoluted kissing game, the girls agree to the three-way kiss.
Tropes:
- Accidental Pervert: During the kissing game, Rentarou accidentally gropes Hakari. Unlike most outcomes of this trope, she actually welcomes it.
- Boring, but Practical: The three-way kiss proves to be the most effective option for Rentarou kissing both girls without either feeling jealous of the other.
- Breast Attack: Inverted, Hakari hits Karane with her breasts.
- Establishing Character Moment:
- Rentarou's convoluted kissing game shows the lengths he would go to in order to keep his girlfriends happy.
- Hakari and Karane both run to Rentarou's defense against the vice principal, but Karane tires to assist him with direct physical force, while Hakari tries to scare her off by pretending that she can see a school inspector arriving. A vivid demonstration of how each of them approach problems.
- Eye Scream: Karane jams a cookie and a bocky stick into Rentarou's right eye in a bashful attempt at Romantic Spoonfeeding.
- In the anime, the bocky stick hits his other eye.
- Foreshadowing: Hakari claims that her household checks body temperature through kissing. Seeing what her mother is like after we meet her suggests that Hakari might not have entirely made it up.
- If It's You, It's Okay: Hakari's reaction to the Accidental Pervert moment mentioned.
- Sacred First Kiss: The plot of this chapter hinges on who Rentarou gives it to.
- Shout-Out:
- In the anime, Karane attempts to perform Hokuto Shinken on Rentarou during the walk to school.
- Two to Kinnikuman. First, in the kissing failure montage, one instance has Karane giving Rentarou a Kinniku Buster. Later when Karane puts the vice principal in a Camel Clutch, Rentarou starts to call her Ramenman.
- Sprouting Ears: Karane sprouts cat ears and a cat tail when she spots a cat.
- Unprovoked Pervert Payback: Karane keeps thinking Rentarou is going further than a kiss during the game, causing her to give him a beatdown when he approaches her.
