ともしびの夜 ～学校からの脱出～

I started playing yesterday! The puzzles are quite difficult, so I'm looking at the answers when I get stuck, but even though I'm still in the early stages, the story is intriguing and makes me want to see what happens next!

Sorry if this is a spoiler!! At Sayo's Hideout in chapter 22. I don't know how to fill in the END here! I thought maybe I had to rub the screen, so I rubbed it for a minute and a half, but it just ended up hurting my fingers... ( ⌯᷄ᾥ⌯᷅) If anyone knows the answer, please tell me <(_ _)>〈 ｺﾞﾝ!〕
