I loved it as i thought it was fair enough in the first season they gave time for jojo and sun oh and in the second they gave time to hyehyeon and jojo it is pretty fair and really liked it also many always wish in love triangles the second lead wins the girl and now the second lead got the girls people are sulking i think it was wonderful many those are song kang are disapointed but if we take a step in reality we all believe it was fair enough and i probably think if i was in her shoes i would choose hye yeong as sun oh would remain in her memories as her first love but from starting to the end hye yeong was their for her when she liked sun oh when she broke up with sun oh and whatever it was so i would probable get over my first love and move on and if sun oh was that sad why did he get a new gf he should have done something like hye yeong did so i think it was relatable after it was a drama and the drama is oc=ver so nothing much will pretty happen from sulking.
Also one moral from the story I goy was dont believe in machines but believe your own feelings
Its just my own opinion
