Fans know him as Effort, and Sangho Lee is a South Korean support currently playing for kt Rolster in the LCK, the top League of Legends league in South Korea. Now 25, he counts as one of the seasoned names in a region renowned for churning out some of the most disciplined and mechanically sharp players anywhere. Nearly all of his career has taken place inside the tough world of Korean pro play, where simply lasting that long says something about his quality.
Supports are frequently called the quiet foundation of a competitive lineup, and Effort fits that picture well. Instead of going after flashy personal plays, a support at his level pours his effort into warding, roaming, and setting teammates up to perform at their best. Each ward dropped, each engage timed correctly, and each summoner spell tracked adds up to small edges that settle games well before any Nexus comes down. The job rewards patience, clear communication, and constant awareness of the whole map.
Effort is closely linked with Rakan, the showy engage support whose dashes and charm-based crowd control call for sharp timing and a willingness to commit. Playing Rakan well means betting on split-second openings, diving into the enemy backline to lock down key targets, and slipping back out before the danger catches up. That pick says a lot about how Effort thinks: he would rather set the pace of a teamfight than respond to one, shaping the terms of each engage for his carries.
Inside kt Rolster, one of the LCK’s most historic organizations, Effort brings the sort of veteran steadiness that holds a bottom lane together. His experience helps him steer younger teammates through the strain of a league where every series matters and the gap between advancing and going home can be tiny. In Korean play, the bond between a support and his marksman often decides games, and Effort’s sense of those partnerships is a real asset.
As the LCK keeps moving at a fast clip, Effort’s mix of accumulated knowledge and assertive shot-calling makes him a meaningful part of kt Rolster’s goals. Whether the meta rewards tanky wardens or risky engage supports, his readiness to adapt and seize initiative should keep him in the mix. For a player who has already survived years of top-tier competition, the seasons ahead present another opportunity to turn that hard-won craft into deep playoff runs.
