I had a similar relationship like this in middle school, we said we'd date but we barely talked/hung out and they'd flirt with others. Difference is that they probably didn't even like me in the first place, and when I broke up with them over text, sounding all serious, they just said "oh ok". It was so cringy lol.
I'd really like to read more shoujo/josei manga like this, without romance (besides the GL undertones) but rather more focused on their lives, careers, and passions. It's so wonderful!
