I would like for ShiVi to have their own original BGM. Something akin to Shiva's intro BGM in the initial episodes... semi-bold, semi-romantic. Because when I think of ShiVi, I think of fireworks. Almost like something of an explosive beauty.
But I would also like for that BGM to be introduced once the kidnapping misunderstanding is gone. I want that music to be reserved for when feelings between them are truly growing versus when they are having their nok-jhoks.
On that note, I also would want them to make a sad/heavier tone BGM. ShiVi have a lot to deal with as a couple, and I expect them to get through some of those struggles as a mature couple (kind of like how their wedding was portrayed), so that tune would be perfect for those moments.
But you're right... the ShiVi scenes these past few weeks don't carry the magic of before. I don't know if it's because of editing or if it's because of the lockdown restrictions. Hopefully, their magic will return and we'll see our old, playful, lovable couple again.
