I was accidentally invited to my husband's workplace event, even though he's having an affair with someone at work. So I'll attend with the children acting like I know nothing, and make him feel uncomfortable.

My husband is having an affair at work. He seems to think I haven't noticed, but I know everything. There's a family gathering being held by his workplace. He apparently had no intention of inviting me, but fortunately, his boss invited us. I'll attend with the children, pretending not to know anything. Now, let the counterattack begin――.
