It's basically more or less the same plot - a pregnant woman ends up living with the family of her "supposed" deceased fiance when in reality she was only an acquaintance/friend of the person. and his fiance was someone else - both go through misunderstandings that lead them to live in another families home. Magic Ring is a train wreck, ring switch and amnesia that winds up putting her with the family. and in Chun Ja's Happy Events it's a boating storm that sinks, a ring switch and misunderstandings of both parents that lead the girl to live with them to escape her own reality. and in both dramas the lead girl falls in love with the deceased sons brother. lol - Magic Ring is a shorter Taiwanese drama while CJHE is a long daily drama (skipping is ok). But with both dramas there is a problem... Magic Ring is left uncomplete or at least not fully available for us... and CJHE is left unsubbed and hard to find (I found it only on Chinese site Soku). Since Magic Ring was made in 2004 I'd say it's safe to say that CJHE is a re-make. (but I can't be sure lol).
