李志焕

李 (Lǐ) is one of the three most common Chinese surnames (with 王 Wáng and 张 Zhāng) and also the standard Mandarin rendering of the Korean surname 이 (I/Lee). 志焕 is a masculine given name combining 志 ('aspiration / will') and 焕 ('radiant / glowing'). In K-drama subtitles, 李志焕 typically transliterates 이지환 (Lee Ji-hwan).

Note 焕 (huàn) is the same character as in 焕然一新 (huànrán yīxīn, 'completely new and fresh') - a common chengyu meaning 'looking refreshed and renewed'. Useful for both name memory and idiom recall.
