I'm watching the particular part of the opening in Chinese subs and try to translate it here (on-screen text in brackets)
<!> It will sound a little like broken English because I am trying to keep as close to the Chinese subs by translating word for word without changing the meaning when translating to English <!>
Since this is just about the opening segment and does not reveal anything about the outcome of the race I am not putting it under spoiler
HH: Didn't Somin's mother come too? (At the time when Jaesuk is radiating impulse, the "impulse" mother and daughter appears didn't Somin's mother come too?)
KJK: Somin's parents both came!
JSM: Both my parents came (The source of impulse and talent, enjoying the concert with her parents is "impulse" So-body)
KJK: Both her parents came
JSM: Because both of them are fans
KJK: Aunt [JSM's mom] is too beautiful, I was surprised (First time meeting, JSM's mom is really beautiful)
YJS: After seeing Jongkook's performance, aunt is a little ... ((Aunt) After seeing Jongkook's performance)
YJS: Is a little....to Jongkook, be our son-in-law (Chosen to be Somin's partner?! Had a shock finally because of "age"...)
YJS: Finally because the age gap is a little....
KJK: Age is a little too big ("Aunt, I will be a good oppa in "My Ugly Duckling")
KJK: But no matter what, the first thing is to enter Somin's mother's heart
YJS: That's right
YJS: Why is it recently Jongkook likes to leave comments in Somin's SNS (Looking at it this way, Jongkook is recently concerned with Somin's SNS? There's no way of just brushing past [without doing anything])
JSM: Particularly happy, oppas are constantly leaving comments
KJK: There's no way of just brushing past [without doing anything]
YJS: Ahh, cannot just leave it as it is
KJK: <nods> Yeah, one essay after another (Somin's SNS how should I put it...?)
LKS: Jongkook hyung is particularly not accustomed to seeing this style (Attention emotional essays = style which is particularly poking in the eye)
YJS: Jongkook's character is he cannot carry on seeing/reading
KJK: Somin tends to have themes which attract critique (SNS which attract critique(Fists?) VS SNS is my creative space)
JSM: It's sort of my creative space
KJK: What did you write? What?
YJS: When I become someone's world, that will be spring (For example, uploaded this type of emotional essay...)
YSC: (tapping JSM's arm) Did you write that?
JSM: Isn't it cool? I wrote that
KJK: (reading from YJS's card) When I become someone's world, that will be spring (Unable to comprehend what is this about?)
JSM: What is the message of the writer? (Let me explain)
JSJ: Who is the writer?
JSM: That's me, that's me (To say what the writer(=me)'s message is)
JSM: The purpose of my creation is, the real spring isn't the spring that comes after the cycle of four seasons
JSM: (screen turns to flowers) it's when I fall in love, and become someone's world, then that's the real spring. Isn't that cool? (Between lovers, if they become each other's everything, the world would turn warm like "spring")
YJS: But here kjk76 says ... (But, "kjk76" who came upon this post)
YJS: What are you talking about? (kjk76 what are you talking about?)
JSM: Oppa oppa! (Attack of ice water, destroyer of emotions, ID: kjk76)
YJS: Don't know who it is! (Freedom of being anonymous, don't know who it is! Don't know who it is)
YJS: Born in 1976, kjk76 says (K J K 76 Kim Jong Kook is born in 76)
YJS: What are you talking about?
YJS: Also, you entered into my frame (Also, in another one of Somin's emotional post)
YJS: Here, kjk76 says "Ha~~~~" (kjk76 ha.....2nd wave icewater attack)
YSC: Is it with that kind of tone? The tone (Seems to be familiar, is it with that kind of tone?)
YJS: Yes yes, isn't it obvious at first glance?
KJK: I'm too lazy even to say it (kjk76 confesses I'm too lazy even to say it)
YJS: Ha~~~ really, really not accustomed to seeing this (Emotions out, replacing "words" using the "body" to the full, is kjk76's SNS)
YJS: But, kjk76 and our Somin (But, kjk76 and Jeon Somin)
HH: have great chemistry
YJS: Have great SNS chemistry (Jongkook&Somin siblings, SNS reverse chemistry, although they haven't followed each other for long)
LKS: Although haven't followed for long
JSM: Really not for long, one month (Reverse of critique chemistry, we are one month SNS companions)
JSJ: Got close together very quickly (Full chemistry on SNS and real life, in this harmonious atmosphere)
PD: In this harmonious atmosphere, Running Man, today we have some guests
Since I haven't watched the rest of the episode yet, I am not sure of the purpose of this conversation.
(NOTE: I have deleted the following line because I am not sure):-
I am not sure of the purpose of this conversation. At first glance I am wondering if he is trying to clear up any rumors with JSM (like he cleared it up with HJY)
