I picked this up because for a while I was consuming anything and everything labelled 'Noona Romance' (older woman pursued by younger man). I really liked it. I was even a little fixated on one of the supporting actresses, Joo Min-kyung, because I really liked her voice. I remember this one scene where the main couple hold hands under the table. The show was full of great angst from the siblings, but what pushed me over the edge was the treatment from the parents.

I suspect I might feel differently now, but at the time I was too disappointed that they actually break up in the second-to-last episode and there's a longer time skip before they reunite and come together again. This is a common trope, I realize now, but in my early drama watching days I wasn't ready for it.
