The plot is interesting but I’ll be honest I’m not really understanding the characters. Natsu is a successful actor yet he’s cold, distant and can’t show love? She grew up with Natsu so she’s had to have seen him display all sorts of emotions so him being completely emotionless and the reason not to tell him about Nashi doesn’t make much sense. Also why has Natsu never confronted Lucy about her behavior? He never thought about asking his childhood best friend why she started avoiding him? And I don’t see a reason to keep Nashi a secret. Yes Lucy can be heartbroken but that doesn’t mean she should deny her child out of a father. Natsu may not be the most expressive dad but he would take care of her and Nashi. For these reasons, I think the story would be more interesting if Natsu did know about Nashi from the beginning, and eliminates a lot of the questions about. I can go into more details but I’m sure you’re tired of me rambling. Sorry about that! I get really passionate with stories I see potential in. Anyways, keep up the good work :)

You definitely have to continue this story ! it's awesome ! I wonder what's going to happen now that Natsu has seen Nashi's picture. Oh and it was random, but I totally loved the moment when Lucy stole Natsu's glass and drank from it, while leaning on his back...it was a very mishevious move from Lucy, kinda intimate, hehe, I liked it ! Please update soon !

Take your time with the updates. I think that you shouldn't rush things in the story either. Like, you could've waited a bit more for Natsu to discover Nashi. Let Natsu and Lucy interact a bit and them let the drama explode xD. I hope that my hints will help :)

Although it's a good plot (not unique though) i think the characters are a bit oc. I believe being outgoing and naughty and destructive are Natsu's characteristics and orthology, quiet and a good student are Lucy's.
Also i think you should have a beta reader so he can fix some grammatical errors and make your story better :)

Wow is he going to find out now? That would be great

Looks like he find out. Great chapter.

Plzz plzz i am begging you to continue... I wanna see where this will head...
