Summer arrives. Aoi turns 20 and a half (she doesn't celebrate half-birthdays, but Mika buys her a melon pan anyway).
She still gets rejection emails. She still works at Crescendo. She still doesn't know what she wants to do with her life.
But something has shifted. She no longer sees the sunlight rectangle as an enemy exposing her flaws. Now, she sees it as permission.
Permission to be unfinished. Permission to be real.
One evening, Ren hands her a CD-R with "Sunken Cinema – Hizashi no Naka no Riaru" written in marker.
"I wrote a song," he says. "About the dust. And the coffee. And being 20 and scared."
Aoi listens to it that night on her headphones, lying in the dark. The song is slow, feedback-heavy, with a bassline that doesn't resolve.
It's imperfect. It's honest. It's real.
She presses replay seven times.
Eat where the light falls on your plate. The entertainment here is observational: watch the dust motes float or the shadows shift. This is "riaru entertainment"—no script required.
In your early 20s, FOMO (Fear Of Missing Out) dictates you say yes to every group dinner, every drinking party, every loud festival.
Hizashi no Naka no Riaru says: No.
Reality is one good conversation in a quiet corner. It is one friend who will sit with you in the sunbeams and say nothing.
The challenge for this week: Invite exactly one person over. Make rice balls or toast. Play a vinyl record or a retro video game (think Animal Crossing or Stardew Valley). Talk about nothing. That is peak Full 20 entertainment.
How does this philosophy apply to films, games, music, and reading? Not everything is analog. You can consume digital entertainment through the lens of sunlight reality.
From sunrise to 6 PM, set all screens to "Natural" or "Warm" mode. At 6 PM, screens switch to "Night Light" (red shift). The goal is that your screen should never be bluer or brighter than the real sun outside. If it is, you have chosen the virtual over the riaru.
