Well now, our boy Ryuuto aint as stupid as he looks.
Marias ruse doesnt last more than a minute from the moment he enters the gym storage room.
When she hugs him, he knows immediately shes not Runa.

Thus caught, does Maria quit right then and there?
He could have said a lot more.
shes feeling now, so she lets her cry on his shoulder.

The next day at school everyone is atwitter about Ryuuto cheating on Runa with Maria.
A photo taken from the bushes shows the two on a park bench.
She also agrees to deny the rumors.

I hope she learned her lesson.
Unfortunately, Runa and Nicole hear this while theyre in the hall.
Runa drops her phone, then runs away upset.

Nicole slaps Ryuuto across the face for breaking his promise to her.
She doesnt respond to his messages telling her shes sorry and asking for an opportunity to explain himself.
He comes close to ringing her doorbell, but doesnt have the guts.

Hes disgusted in himself.
When he realizes hes Runas BF, he introduces himself … as Runas hot tanneduncle, Mao.
That aside, Ryuuto is there to apologize to Runa for making her worry.

While he turned her down flat, he knows theres no excuse for not telling Runa everything sooner.
But to his surprise, Runa isnt upset.
That he showed up to talk to her before her phone got fixed only reinforces her trust in him.
The question is, who took that photo in the bushes?
I also doubt it was Nicole, as she doesnt seem like the voyeuristic pop in.
