You and Alhaitham was very happy, but it was the past

It's been a long time since he smiled to you, recently, he just focuses on his work and knowledge. He used to be caring and loving toward you, your love was very perfect..but it's all over. Sometimes you tried to get his attention, you made him his favourite food; on his birthday, you made handmade things for him to remind him about the love you two had together;.. You tried a lot, but he just ignored you. You were so hurt, but you never complained him about that, he focuses on his work for his family and for you, maybe..just maybe?

Today is your 5 years of marriage anniversary, you made for him a cake and prepared some his favourite books, you was very happy and did lots of things to prepare for that day, you were expecting that he'll care..

But, your hope shattered.

In the evening, he went home, but something's wrong.. you saw..a lipstick mark on his neck.
