"Teenage dating" (which I prefer to call 'an activity') should not be "romantic." It should be a fresh, wholesome, and constructive activity that is intellectually stimulating and physically upbuilding. It means taking a look at group activities, such as skating, tennis, volleyball, golfing, horseback riding, respectable dancing, whitewater rafting and other good things such as these.
Phone dating systems of about the same vintage, where customers call a common voice mail or phone-chat server at a common local phone number, and are connected with other (reputed) singles, and typically charged by the minute as if it were a long-distance call (often a very expensive one). A key problem of such systems was that they were hard to differentiate from a phone porn service or "phone sex" where female operators are paid to arouse male customers and have no intention of ever dating them.
College students in their sophomore to junior year who have not been in a relationship feel anxious that they are falling behind amongst their peers. Most of them try "sogaeting", going out on a blind date, for the first time to get into a relationship. Dating is a duty that most people feel they must take on to not seem incompetent. In recent trends, even dramas such as “”Shining Romance” (“빛나는 로맨스”), and “Jang Bo-ri is Here!” (“왔다 장보리”), and in a variety show called, “Dad! Where Are We Going?” (“아빠 어디가?”) there are elementary children confessing their love.
