Spoiler:

Maiku returns home early in the morning after searching for Miina all night with no result. Putting on a brave face, he tells Karen "Once she gets hungry, she'll return home". Karen is quite sad, because her greatest desire is for the three of them to continue living together in the same house. As she enters her class at school, with a sad look on her face, she looks to the seat where Miina usually sat... only to see... Miina! "Myu...."

Karen discovers that Miina had stayed over at fellow classmate Haruko's house for the night. (Haruko is the girl with the hentai brother who is obssessed with her.) However, Miina will not utter a word to Maiku. When asked, all she would do is present him with a note that said "I'm keeping it a secret" (or something like that).

After a full day like that, Maiku is frustrated, but is at least relieved to see that she is still around. He decides to go visit Miina at Haruko's house, but Karen dissuades him, arguing that it would best in times like this for them to talk together as girls. Karen packs some extra clothes for Miina, and heads off to Haruko's house.

Karen and Miina have a little heart-to-heart (in the bath, of course!) where Karen once again affirms Miina's welcome in Maiku's house and life, both from his perspective and her own, despite the fact that she is the "stranger". "There's no one else who I'd want to be Maiku's girlfriend; only you." Miina says that, above all, she really still wants to live in the house with them, but is no longer able to face Maiku now that she is able to fully accept her feelings for him. She asks for Karen and Maiku just to give her a bit more time.

Upon returning home, Karen explains to Maiku that Miina is alright; that she just needs time to work through her feelings - to discover her "now". When Maiku asks her what exactly Miina's "now" is, Karen says "that is something that you'll have to hear directly from her". Maiku notes that, even after the truth was revealed, he still thinks that Miina and Karen are more like true twins. Karen responds that "We are twins, even though we're not related by blood." Right then, though, Haruko comes running up in a panic... "Miina just left my house, and she's heading to the train station! I think she may be leaving!"

After rushing to the train station, Maiku finally confronts Miina about all that has gone on. He affirms once again how much he wants her to stay living with them. When Miina confesses her worry about the fact that she's a stranger, he dismisses it... "We'll just get married, then. That way we can all stay together forever." "Was that... a proposal?" "No no! It was an example!" Miina exposes her deepest fear... "What if our feelings change? Then, I won't be able to stay with you anymore." Maiku also dismisses this fear "You worry too much about the future. What do you want to do now?" "I want to stay, living with you and Karen, in our house." "Then, do so." And, after all this build-up, Maiku and Miina finally kiss...

"You can't do that!" Karen yells as she runs towards him. Of course, she trips and proceeds to knock Miina right out of the way and, you guessed it, falls right on top of Maiku with a kiss. Upon realization, and with a "Myu...", she proceeds to faint. When Maiku puts her skirt back into place, he is met with applause and congratulations from... Kousei! "Not even I could pull off something like that!". It turns out that everyone had gathered to support Miina's love and were watching all this time! The whole thing was actually a setup orchestrated by Haruko! "Definitely grounds for a suspension", the student council president says.

With feelings revealed, Karen, Miina, and Maiku return to their house. "You're not fair, Karen. I thought you were supposed to support my love!" Miina says. "Yes, but Maiku's still my brother!" So, now, they take a new photo - of the three of them - beginning this new chapter in their lives. They do not know for certain what the future may hold, but they pledge that the three of them will stay together, forever.

"You know, Miina, it was actually you and I in that photo from way back then", Maiku added in the epilogue. "Yes, I was sleeping at the time", Karen says. "We were all together, even back then..."

And so ends my plot summary! I hope this makes sense, and that I got the order of things right, as I am doing it all by memory! Onegai Twins has gotta be one of my favorite shows, just for the pure light-hearted fun of it all, but with just enough depth to make you care for the characters. I enjoyed it a lot, and had fun writing this summary.
