I'm assuming you mean the orchestral piece that plays pretty often? It's from the movement Jupiter, The Bringer of Jollity from Gustav Holst's The Planets suite! Its the slow middle section of the movement.

I love Yoo Seung Ho so I'll keep watching this but oh my god Son Soo Jeong is one of my least favorite female leads. She's so stupid. How could she not ask Bok Soo what happened in 9 years? Wouldn't you ask someone what happened first before assuming? She's such a coward for not even asking. There's no way she can redeem herself to me. I love Bok Soo and I even understand Se Ho and feel bad for him, I want to see him be redeemed. But Soo Jeong? She has no excuse for what she did. She ruined Bok Son's life just because she was too much of a coward and dummy to ask and believe in him. And it's pretty unrealistic that Bok Soo even still likes her after what she did to him. Ugh.
