Since that photo appeared in the present timeline, it means Sol34 going back has already altered the present.
MEANING the scene where Sun Jae stopped beside the road to share an umbrella with her when she told him "I'm your fan" now has Sun Jae REMEMBERING the same "I'm your fan" from when they were younger.
MEANING not just the umbrella and the candy but the "I'M YOUR FAN" was something she clearly couldn't remember. FOR 15 YEARS.
It's going to be so much fun watching Im Sol when she realizes Sun Jae likes her. As of end of ep 4 he is her fav idol.
I hope there is compilation of all the moments with her and Sun Jae and this time she sees them in a different light and along with her, we all turn in a sticky goo!
Honestly I can't concentrate on where to look on this fanclip. His face is so gorgeous and his red outfit really suits him a lot. Plus that drop dead hot body and singing voice! 🥵❤
