I can smell the love triangle... his coworker is probably gay and put the wedding ring on to seem like he has a girlfriend at work ... MC will probably find this out after he decides to give his sister's friend a chance and it will sway his emotions... it will probably be a rollercoster until he finally ends up with the sister's friend ┗( T﹏T )┛
I don't know if I can continue this without the promise of grovelling from the alpha at any point
