Hey, Onii-chan,

Even though the protagonist of this manga already has such a good relationship with his childhood friend,

Why is he going out with that transfer student?

What happened to all those promises and his bond with his childhood friend?

This is what you call a... "Betrayal" Isn't it...?

Afterward, I let her read a manga where the childhood friend wins

Somehow, that managed to calm her down

RUSHED

They both made such efforts to protect their childhood vows with each other... And even got married...

I'm so moved...!
