Back then, I only felt sweetness. Isaac and I always had endless topics to talk about, endless gossip.

Until, Alma appeared between us.

"Anna." The teacher patted my shoulder.

I turned around absentmindedly and saw the teacher pointing to a maple tree in the distance, asking me, "Since you're here, do you want to take pictures with them?"

I looked at my classmates standing together, smiled and nodded, taking pictures of autumn, witnessing autumn. 

I hesitated for a moment, this time I really did not want to post on Instagram. 

But then I saw that Alma had updated her Instagram a minute earlier. [I have a secret in my heart, that secret—]

The accompanying picture was a man's back view wearing matching pajamas.

It was none other than Isaac; I recognized him immediately.

Alma frequently updated her Instagram.

When Isaac cooked porridge for her, watched a boring movie with her, took her grass skiing, or made her brown coffee, she would post it with a sweet caption, [It seems that after half a lifetime, I finally know what I’ve been looking for.]

Alma's thoughts were laid bare.

Everyone understood, except for Isaac, who pretended not to know.
