It starts with the wedding scene. Fuutarou kisses to the bride.
Bride : Fufu, Fuutarou. you look nervous. Remember that day 5 years ago. It wasn't the first time.
Back to five years ago.
Raiha : Oni-chan, which one do you prefer? Wait, are you listening?
Fuutarou studied all night and still studying during the breakfast time.
Raiha : Really, I said don't study while you eating.
Isanari : Yeah, even if you couldn't get full mark at the last test.
Fuu : How did you know that... (Fuu didn't tell about his test result)
Anyway, they are talking about the trip during the spring vacation.
Fuu : Concentrate... Concentrate... I should concentrate on just this not to make a mistake again...
Raiha kicked him out from the house, and ordered him to go shopping for a refreshment.
Fuutarou met Miku. They go to the market together.
3 : It's good to see you healthy. You've never came to our house after the exam.
Fuu : I, I don't have things to do there.
Fuutarou asked aren't there closer market from your home. Miku replied "It's not like I detoured to this market by remembering when we came to meet you cause I might meet you near here".
Fuu : You're not even hiding it...
Anyway they found a poster at the market. The A prize of lottery is onsen trip ticket, which is near the quints' grandfather's home.
Fuutarou prefers E or B prize cause he can sell that for money. But Miku said she should buy things for Nino first.
Fuu : Miku, is there someone you love?
Miku : Eh! N, no. I told you before.
Fuu : But is there anyone you love in your class since then?
Fuutarou started his story about being confessed. He didn't say it's about him and Nino, just some other's story.
Miku is surprised that Fuutarou care such thing. She thought Fuutarou would never consider romantic things.
Miku replied what she felt about her confession but she said it's about someone else.
3 : I think she couldn't confess because she lacked confidence... If she confessed, they can't go back to the original relationship. She needed such courage.
F : (So it is... But I don't know how should I face her...)
3 : (There's such courageous girl in this world... Am I a coward?)
Fuutarou won the A prize and went to the onsen with his family.
His phone is out of battery but he doesn't need to call someone.
Fuutarou yelled Yahoo at the observatory, but then Itsuki finds him. they are surprised at seeing each other.
Yotsuba and others followed, and...
