Help looking for specific ost in When the Phone Rings

Hello! Not sure if this is the right place to post this but in episode 10 of When the Phone Rings, around the 25 minute mark, there's a piece of music playing that has violins in it while ML's dad is staring at a portrait of his family.

I tried looking up the score/ost for it on Youtube and Spotify but I couldn't find it D: I love it and it's driving me crazy that I can't find it lol. Does anyone know what it's called?
