You create a very powerful story, but in one place, it moved without showing how Jenny was connected. Aside from that, I like your story. Job done well.
The days were all the same: more and more work, more and more money, which, aside from restaurants and clothes, he didn't know how to spend because he was always at the office. Once he tried to contact Jenny to see if she needed anything, but she had cut off all contact.
Dennis decided to face his fears and texted Jenny to agree to the meeting.
The following Sunday, Dennis arrived at the agreed-upon restaurant, very nervous. Then he saw her enter, beautiful, looking a little tired, but determined. As Jenny passed a few tables, Dennis also noticed him and his small steps, his little hand in his mother's: their son.
Hi, thank you so much. At the beginning of the story, Dennis receives an unexpected text from Jenny. It's this text that Dennis responds to after the flashback. It was Jenny who couldn't be reached, but Dennis still works at the same place and hasn't changed his number, so I thought it would be easy for Jenny to get back in touch.
Yes, now I understood it. All the best.
