รักอีกครั้ง

I loved the show but there were a few things that confused me. SPOILERS DO NOT READ IF YOU HAVENT WATCHED. highly reccommend watching it. so if Sol and Sun are twins then Sun dies and Ray appears are they triplets? When Sol comes back from the Studio after Sun's death and Ray had appeared the week before then why wasn't their Mom concerned with Sol seeing Ray? why didnt she stop him and explain that they were triplets with Sun and Ray being identical? also Heenry and Ray grew up together so why didnt Heenry react when seeing Sun in the band looking exactly like Ray? The plot had a lot of holes but it was overall a very cute show!
