But there are still two more rounds of the national qualification remaining and with Kim only trailing by 5.23 points, Lee needs to keep up his momentum.

And Lee said he isn't going to deviate from his safe, conservative routines that don't include a quadruple jump -- a rarity in the men's figure skating where technical prowess is increasingly becoming a necessity.

"I thought about doing a quadruple jump at this competition, but my coach was against the idea," Lee said. "I changed my skate boots about a month ago, and I wasn't landing my quad jumps in practice with much consistency anyway."

Kim, also 21, said he's looking forward to competing with Lee for the Olympic spot, and he's ready to accept whatever the results may be in the end.

"Obviously, everyone dreams of skating in the Olympics, and nobody wants to give anyone else an inch in these competitions," Kim said. "We'll all have a fair battle and whoever ends up going to the Olympics, I will cheer on him from the bottom of my heart. I hope we can all finish the qualification stage without an injury and pull for the guy who gets to skate in the Olympics."

Cha, the youngest of the three contenders at 16, has had a disappointing 2017-2018 season so far. Hampered by ankle and hip injuries, Cha finished a distant third at the first national Olympic qualifying event. He skipped an International Skating Union Grand Prix event earlier for precautionary reasons, so he could rest and prepare for the second qualification stage.

"I don't think I am 100 percent yet, but I am definitely better than I was before the first qualifying event," Cha said. "I don't want to push myself too hard this week. I'll try to do the best I can under the circumstances." (Yonhap)
