At the breakfast table, Nagi is adamant that he’s not going through with the marriage, but his parents, who very much still possess delinquent streak, will book no insolence. His mom asks if there’s any reason he can’t marry Erika, but Nagi can’t exactly tell her he’s in love with someone who doesn’t know his name! Sachi, meanwhile, wants nothing to do with this whole situation, even though Erika is her big sister…and soon to be sister-in-law.
Nagi’s folks head off to work, telling him to keep Erika company when she visits. He cleans up the place, but when she’s an hour late he looks outside the door to see she’s been sitting there the whole time, apparently unaware of doorbells. She also finds his modest Japanese home confusing, what with its tiny size and lack of chairs. She actually assumed they were in a tool shed!
After Nagi gives her a grudging tour of the house (which doesn’t take long), Erika takes him on a tour of her palatial mansion, where the damn doghouse is larger and fancier than Nagi’s whole house. The thing is, there isn’t the slightest inkling that Erika is showing off…this is just how her life is. Nagi, who wanted to tell her he has feelings for someone else, now sees that even if he wanted to marry her, reconciling their wildly different lifestyles seems impossible.
So it comes as a shock to him when Erika interrupts him to say she won’t be marrying him, which is exactly what he wanted to tell her but couldn’t find the right time. Like him, it simply comes down to her wanting to choose who she marries. She can tell Nagi is a nice guy, just like he can tell she’s a nice gal, but they’re also modern young people who don’t like things being arrange.
She didn’t even go to Nagi’s to see him, but to talk about this with his…with her birth parents. When Nagi says they’re working at the family diner until midnight, Erika has him take her there. While at first things are cordial, the Umino in Erika comes out as she gets into a heated standoff with Nagi’s folks. Hikasa Youko and Kimura Ryuuhei are pitch-perfect in their respective Delinquent Modes, telling Erika she’ll do what they say and like it, damn it!
But once everyone’s hackles are lowered and hot tempers cool, Nagi’s parents boast to a couple of regulars that the beauty before tham is Nagi’s fiancée. Then they whip up their special ginger pork, which Erika has never had before but loves instantly, then her biological folks get in close and start comparing her face and hair to their own and Sachi’s. They invite her to spend the night, and Nagi’s mom wants to have a bath with her. Nagi has the feeling his folks are manhandling a bomb that’s about to go off.
Instead, she suddenly excuses herself and runs out of the diner. Nagi gives chase, and learns he grossly misunderstood her feelings at the time. She wasn’t a bomb about to explode…she was simply overwhelmed by how warm and welcoming her birth parents were, and overcome by apprehension over whether they’d like her if she stuck around. She wants nothing more than to be closer to them, but doesn’t know how to tell them that. Nagi assures her no such formalities are necessary.
His folks are “really dense” former delinquents, and thus she doesn’t have to be so considerate with them. It’s enough to just be there and be herself, and they’ll love her all the same. Sure enough, when Nagi and Erika return to the diner, his mom gives Erika a big hug, while his dad wipes away a tear reacting to the heartfelt reunion. They have a big meal together, but Erika takes a raincheck on a sleepover.
While Nagi walks her to the main streets, Erika tells him she had fun and was glad she got to get closer to her birth parents. Sachi, who still has complicated feelings about all this, is left unmentioned. Erika also asks what Nagi was so anxious to talk to her about all day, and Nagi can’t say it. He thought it would get easier with time to say he loved someone else, but instead it got harder.
It gets harder still when Erika’s dad rolls up in his Lexus. He reveals that he knew they weren’t really dating (a dude that rich has a head on his shoulders), and also gives them both a ride…to a large house set up specifically for them to live in together as a couple. Their names are even on the engraved doorplate.
If Nagi’s folks knew about this, they kept it to themselves. But hey, this premise is already freakin’ absurd, so I am completely on board with this escalation. Domestic bliss awaits our beloved cuckoos!
