All of the above!

Looks like Makoto actually got injured during that fall despite everyone seeming cool afterwards, so he must go to the hospital for a bit. However, things aren’t as they seem as his visiting hours get kinda weird.

We begin with Makoto addressing his adolescence chart at the end of each episode as he’s re cooperating from a broken arm he got when he flew his bike into the ocean.

But all of my high school years sucked aside from crashing a homecoming

When Makoto gets back to his bed, he imagines both Ryuuko and Maekawa sleeping under the sheets.

Now what could possibly get better than this?

THIS!

Luckily for me, Meme  is in the bed. Unluckily for Limpdick Makoto, Meme is in the bed, so he gets dismayed as he spends his time with her drilling her on her actual husband, whom she loved but because they decided to go their separate ways due to their best interests for Erio. However, she’s got herself a replacement.

Now how about that consummation?

It’s at this moment that Meme leaves, much to Makoto’s relief, as he fears she might take away his adolescence points with her hotness. Fortunately for him, he’s got someone near his age gap to talk to with Ryuuko. Maturity-wise, however, will be despairing to Makoto as Ryuuko discusses her hat, hair, and her curiosity as to whether his bike jump was intended as suicide or as a thrill, meanwhile flailing around like a kindergarten student hopped up on Mountain Dew and several bowls of sugar.

Is there such thing as "too moe to live"? Because that's essentially what Ryuuko is

Maekawa then pops in in an eggplant outfit that she takes off to reveal her school outfit. She then uses a lie that she spends the night with Makoto all the time to drive Ryuuko out of the room.

It would only make sense that the lump behind the Eggplant outfit is her ass

She uses this as an opportunity to ask about the accident, as well as ask him out to the beach, which causes Ryuuko to come back in the room. Maekawa slips out that Erio is Makoto’s cousin, resulting in an awkward silence. This comes into full circle when Makoto says that she’s living with him.

Well, they're cousins so it's not like they're hitting it off. Meme might be a different story

When Makoto re cooperates and his arm has healed, he heads home to see that there is a surprise for him in the fridge. This surprise is Meme, who hung out in the fridge as a joke in order to cool off.

Meme says that the real celebration will be at a restaurant that she’s going to treat Makoto and Erio to. Speaking of Erio, she acknowledges that she’s trying to restore her lost memories to Makoto as she gives him the gift of panties after overhearing his joke with Meme during the Old Maid match.

Can't fault her for doing the research

They then head off, as one-armed Makoto is tasked to drive the bike while Meme hugs him from behind. Why they decided to opt out of using Meme’s car is beyond me.

To those who have seen the movie, is this a plausible reference?

The episode ends as Maekawa sweeping a storefront in a dumpling outfit when she sees a water rocket propelled to the sky that probably came from the beach.

Looks like Kim Jong Ill finally went postal

Overall it wasn’t necessarily an eventful episode and seemed a bit like nothing really went on aside from him breaking his arm, recooperating and going out to dinner. Meme’s still pretty charming, Erio is slowly trying to integrate towards a more human life, and Maekawa might serve as a good love interest that helps Makoto get through with Erio, but Ryuuko seems out of place and it honestly kinda peeves me how dense she is as someone who’s supposed to be a human being. Like when I said “too moe to live”, I mean that there is no way that someone like Ryuuko would actually exist in real life without being committed to a psychiatric ward. That being said, I’m looking forward to the next one
