No they're just saying WHY she cheated
There’s a difference between excusing the cheating vs. explanation.
Unfortunately this type of thing happens a lot. Cheating because of feeling neglected.
Huh. You're missing the point. Whatever is the author's opinion about cheating, the author just simply explained how Shizuma's personality and brain works. As a partner, he evaluated himself how he treats his partner and make corrections. By no means Shizuma says cheating was fine and justified, he was just taking accountability that he was partly at fault.
Did..Did the author just give an excuse for the ex-girlfriend for cheating!!!
Honey you feel lonely?? Go fucking break up with him!!!
