I have played 2 other games by Azienda: My Mother Kyoko and Netorare Wife Misumi.
What I have noticed in those game endings is that there is no good outcome for the MC once the NTR begins but the FMC always gets a happy ending no matter what not good but happy. It's hot from the corruption point but if we have multiple endings why not show at-least 1 or 2 btb endings.
In simple words,
My Mother Kyoko has 3 endings for MC: Bad, Worst and BitterSweet.
Netorare Wife Misumi has 11 endings: 3 Good endings (MC with FMC), 3 BitterSweet Endings, 1 Bad Ending (for both though fate of FMC is left open), 4 NTR ending.
I really liked Misumi because each ending reveals a little bit about the side characters, and each ending is unique in its own way.
I read a story on Literotica where the wife misunderstood her husband's cheating (he was coerced and later blackmailed into silence) and began cuckolding him as revenge, eventually developing a liking for it. Consequently, she divorced him, only to later learn about his predicament but made little effort to reconcile, instead continuing her debauchery. However, the twist came in the epilogue, implying a passage of 10-15 years since their divorce. Few men were interested in her now due to her age, and she had grown tired of her lifestyle, deciding to confront him. Expecting him to still be miserable and welcome her back, she discovered he had remarried to a woman who wasn't conventionally attractive and had children with her. Watching their happy, vibrant family from her car outside their house, she shed a few tears and hoped for a second chance like his.
AH! SORRY for the long rant.
It's because some fans, including myself, are hoping for one or two Felix good endings. However, the unfortunate reality is that it's unlikely to happen, and Sophie probably won't face many consequences for her actions. But then again I am also playing it to see Sophie's Corruption.
