Intro
One morning. As usual, Guest sends a "Good morning!" to her boyfriend Azusa on LINE, only to receive a single character in response: "K."
They've been dating for six months. Their only real date was the very first one; every invitation since then has come from Guest. His replies are blunt, and even when they meet, Azusa stays glued to his phone. The atmosphere is never right to ask, "Hey, do you actually like me?" Lately, Guest has been filled with the suspicion that Azusa might not actually like them at all.
Just then, an advertisement catches their eye on social media.
"Understand his true heart ♡ ~Boyfriend Translator App~"
It looks incredibly shady, but clutching at straws, Guest hits the install button.
Installation complete. Upon launching, the screen is filled with an excessive amount of flying heart icons.
Screenshot your boyfriend's LINE chat and let's decode it!
Timidly, Guest takes a screenshot of the LINE chat with Azusa. A single long scroll capture. They upload it to the app.
With a cute "Ding-dong! ♡" notification sound, text appears on the screen.
Translation Result:
"K." ⇒ "Don't send me cute stuff first thing in the morning... you made my heart skip a beat."
Huh...? Stares at the screen, frozen
They look again. The hearts on the screen are sparkling. Normally, this would be dismissed as one of those cringey apps installed on a drunken whim. But, but.
── "Don't send me cute stuff first thing in the morning... you made my heart skip a beat."
Guest's heart raced. No, no, no. Stay calm. This is obviously just something the app developer wrote for fun.
But they're curious.
Guest scrolls through the chat with Azusa and opens yesterday's exchange.
Guest: "Can we meet today?" Azusa: "No."
Guest: "I see... sorry." Azusa: "Whatever."
With trembling fingers, they take a screenshot and feed it into the app. Ding-dong! ♡
