Three chapters and already Return of the Baby Daddy has become my story which has received the most questions from the readers :) 
It's a good thing and I'll have you know that it isn't bothersome at all. Keep the questions coming :D It shows how much engaged you are in my story and I really appreciate that ❤
With the little time I get between Work and College, I have been unable to reply to each and every comment (and/or) question. So I decided to write a blog post about some questions I've come across.
 

1. Does Kris know that his mother paid Sera for an abortion?
ANS: No. He doesn't know. At least not yet.

2. How did Kris find out Yuan without even knowing Sera's name or how she looks like?
ANS: This will be explained in chapter 4 (coming soon)

3. How is Yuan old enough for school?
ANS: Sera was 16 when she became pregnant.
-Sera turned 17, Yuan turned 1
-Sera turned 18, Yuan turned 2
-Sera turned 19, Yuan turned 3
-Sera turned 20, Yuan will soon be turning 4.
At the age of 4 you'll be in kindergarten.

4.Will Kris really be suing Sera out of nowhere?
ANS: No. He didn't exactly say he will for surely sue her. He only told her that if she doesn't allow him from seeing his son then he'd have no choice but to fight for custody. So as long as Sera goes along with his conditions, he won't sue her. But if she refuses, then he will sue her.

5. Does Kris's mother know about Yuan's existence?
ANS: Not yet. When Kris found out about Yuan's possible existence, he resigned from his position in the Wu family business and immediately moved to South Korea without looking back. Ever since he hasn't contacted home yet.

6. So is Kris jobless? (NEWLY ADDED)
ANS: Currently, yes he is jobless. He submitted his letter for resigning from the position of the COO in the company but he yet hasn't received a reply for his letter. So actually he doesn't have a job yet but in the eyes of the company, he's still the COO until they approve his letter and officially grant him resignation.

7. There is no way Sera can turn 20 while Yuan turns 4 if she gave birth at the age of 16.  (NEWLY ADDED)
ANS: Pregnancy lasts 9 months and 9 days. That's the most normal case. She was 16 on the year 2011 when she got pregnant in February of that year. Which means Yuan's birth was on November of 2011. So in the next year which is 2012, Sera turned 17 and Yuan turned 1. On 2013, Sera turned 18 and Yuan turned 2. On 2014 Sera turned 19 and Yuan turned 3. On 2015 (current year) Sera has turned 20 and Yuan will soon be turning 4. Which indicates that it has been 4 years since the incident.
Here is a timeline for Sera's life, starting from when she met Chanyeol.

8. Is Chanyeol still in love with Sera? (NEWLY ADDED)
ANS: Only Chanyeol can answer this question. (Just kidding, you'll find out as the story proceeds whether he is over her or not)

9. If Chanyeol and Sera started dating when Sera was just 15, how older than Sera is Chanyeol? How did Chanyeol become a prosecutor at such a young age? (NEWLY ADDED)
ANS: When Sera was 15 years old, Chanyeol being 3 years elder than her would have been 18 years old. He graduated High School at the age of 16, began his first year of Degree when he was 17 years old. So by the time he started dating Sera, he was already on his second year of obtaining a degree. The year 2011 was his third and last year of the degree. 2011 was also the year he cheated on Sera and Sera became pregnant with Kris after which she had no choice but to move to South Korea. For a while there Chanyeol and Sera lost contact but Chanyeol later moved to South Korea and offered Sera his help in raising the baby. (More of this incident will be coming in the future chapters) So whene moved to South Korea, he had already completed his 3 years of degree in Beijing, China. Then for the next 3 years (2012, 2013 and 2014) Chanyeol attended law school in South Korea and became a prosector after finishing his bar exam on 2014. So by the time 2015 arrived, bringing Kris back into the picture, Chanyeol had become a prosecutor. A new one at that.

10. Does Kris love Sera?  (NEWLY ADDED)
ANS: Well, you're just going to have to find the answer for this one on your own, buddy. ;)

11. What's YiFan's age?  (NEWLY ADDED)
ANS: The answer for this was supposed to be revealed in the upcoming chapters but since you guys are so curious, Kris is 24 years old and will be turning 25 this year. Like his real age. Which means he is 5 years elder than Sera and 2 years elder than Chanyeol.

12. Will there be a polygamous relationship between Kris, Sera and Chanyeol?  (NEWLY ADDED)
ANS: Haha I'm surprised you'd even ask a question like this lol. Polygamy is not allowed in South Korea from what I know ^_^ haha. And even if it was allowed I hardly think it would be in a way where a female marries more than one male. In some countries Polygamy is allowed but in a way where a male marries more than one female. Either way, marriage is the last thing in all their minds right now hahaha I'm still laughing about this question :P

13. Why is Yuan saying that he is half Korean when both his parents are Chinese?  (NEWLY ADDED)
ANS: He was born in Korea and is being raised there as well. That's why he thinks so. In my country if you're being born and raised in a particular city even if your parents don't actually belong there, you are considered to belong in that city. I'm like this too. My mom and dad are from completely different Islands but I was born and raised in the capital city. Which makes me a resident of Male'/Maldives.

14. Is Yuan bilingual? (NEWLY ADDED)
ANS: He's trilingual. Korean, Mandarin and English. However, given his young age, some of his sentences are not very well structured.

[IMPORTANT] If there are any more questions, please comment here. I'll be more than willing to clarify :)
As I keep getting questions, I'll keep updating them so you can check this blog post once in a while to see the new answers for the new questions :D
Have a nice day!
