Here's Another Theory on Lovely Runner

 Here's another interesting theory on Lovely Runner based on the latest episode!

According to Twitter user @fangirlarkive, 

When Sol pressed Sunjae’s watch when he died, it acted as a new time machine. When it did, both Sol & Sunjae traveled to the past.  Sol & Sunjae avoids each other in that timeline and pretended to not knowing each other.

Both Sol & Sunjae won’t be in touch during this time slip, but after this time slip ends, Sol went back to her 34 year-old self in 2023 but Sunjae can only return to his 35 year old self (this is a reference from their house number Sol’s 34-1 and Sunjae’s 35-1).

In episode 13, Sol met the 34 year old Sunjae as an actor, but whose memory hasn’t returned yet. (OP believes that this is because he has to be 35 years old to remember). This is because it was only December, and Sunjae’s memory will only be restored in the new year when he reaches 35.

Another post mentioned that in that rainy moment that Sunjae supposedly did not see Sol, he actually did. There is a tiny movement of his lips which may be a smile. And this may mean that he is also a time traveler. 

Any comments?
