Sorry to bring my own story in the mix, but while I never cheated, I've been in the shoes of two of the characters. I stole a guy's girlfriend and I've been cheated on (This is karma I know) and both experiences have been valuable in term of growth. Yes, you feel like shit and beyond angry when being cheated on. But when you're the one stealing, you feel really empowered, especially when you're a girl stealing a girl. Maybe I'm awful but it was a nice feeling at the time. And when I was in the reverse situation, I felt terrible, but the irony was not lost on me. But I can say that I always was commited to my relationships so I don't think as myself as a bad person. I just act on what I really want and I don't lie.
Things like this happen all the time. Just lying is the bad thing here. And it's Yuma doing it.

Like cheating is not inherently bad, it can be falling in love with someone else when ure on a fragilized relationship.
The bad part comes after that, when the charater lies about it even after accepting their feelings...
Like, i wouldnt see anything bad on Yuma if she just realizes she fell for Hotaru and diches the guy. And neither would i feel bad for the guy in that situation, he simply dint had a strong enough bond.
Now i would say its wrong if the realizes her feelings and keeps the guy unaware, deceiving him.
Theres also the case that she could like the guy as a person but not sexually, but we know nothing about him so its not rly applied here. Even then the right thing would be putting the cards on the table, telling the truth and figuring it out.
