'Do Do Sol Sol La La Sol' Episode 5: Jun begins to fall in love with Rara as she looks after his well-being
The 'Do Do Sol Sol La La Sol' Episode 5 promo sees Dr. Cha find out the truth about Jun's identity from a former junior staff member
Just when Rara was ready to leave Jun's home and go to her home that she had made recently with the salon lady Sook-kyeong (Ye Ji-won), it begins to rain heavily and the thunder and lightning seem to remind Jun of another day when an unfortunate incident seems to have taken place. When Rara (Go Ara) tells Jun (Happy Song) goodbye and is about to turn to leave, she notices Jun looking ill. He looks pale because when Rara had said her byes, Jun had heard someone else. This puts Jun in a tough place because he is unable to let Rara go and is also unable to let her in on his secret. So in 'Do Do Sol Sol La La Sol' Episode 5, we see how he chooses to move forward with this new relationship.
Turns out, Rara can be quite considerate despite how her worldview is not quite educated by reality. So even though Dr. Cha picks her up and is about to drop her back at home, she changes her mind and hurries back to Jun because he hadn't seemed too well. When she returns, she also tells him to open up to her about his worries. She explains how people might find sharing worries a burden, but tells him that she doesn't mind sharing his burden because it is Jun. This moves Jun more than anything and he is slowly but surely falling for Rara.
From making her small dream come true, which includes getting her breakfast that she has been craving since having left her home to buying cosmetics for her that she was initially not able to afford, Jun does it all. He doesn't want to make a big deal of how his heart has changed, so he continues to treat her well, but doesn't make it seem obvious. He acts as if he is not going out of his way to take care of Rara, and that is exactly how she acts.
We also learn that the body that had washed up on the shore is an unidentified person who is not the Jun that the rich old lady has been searching for. So the chances that Jun is from an affluent family is at the moment high. However, why he is on the run from his own family or who the other boy in the picture was is something that is yet to be revealed. Will he manage to win his parent's approval and continue to live outside of his actual home or have they planned to let him be for now?
'Do Do Sol Sol La La Sol' will air on KBS2 on Wednesdays and Thursdays in Seoul, South Korea, and can be streamed on Netflix in the US.
