Suddenly, Kou finds himself in the world of gal games. Who could the heroine be?
If you don't finish the confession 
event on the roof, this won't end.
Wenn du ihr nicht auf dem
Dach deine Liebe gestehst, passiert nichts.
Si no le confiesas tu amor 
en la azotea de la escuela,
Si no le confiesas tu amor 
en la azotea del instituto,
Tu dois lui avouer ton amour
sur le toit pour en finir.
Se não terminar de se confessar 
no terraço, isso não terá fim.
