MANY teenagers pick Jackie and Leon Lai as their heroes - but Napoleon Bonaparte? He has a great fan in fledgling student-singer Luk Ka-chun. The 18-year-old history buff has read over 10 books on the life of this 19th century French emperor and is overwhelmed by his ''unbeatable spirit'' that won France glory. History may sound altogether a different arena from the glitzy showbiz circle, but Luk embraces both with equal passion. Even amid tense preparation the month before the HKCEE, the Form 5 New Method College pupil found time to record his second album Heart to Heart , which has just been released by Sony Music Entertainment. Luk is also stepping into stardom. He has just contracted a supporting role in director Tsui Hak's new work The Green Snake , joining ranks with megastar Maggie Cheung. Compared with Eighteen Blues , his debut record last year, Heart to Heart presents a more grown-up Luk who bares his desires for a more mature love experience to listeners, not mere puppy love. ''How to Begin Love With You?'' is a representative song along those lines. ''I sing of a young lover's frustration in not knowing how to express his feelings for his love. ''He could only indulge in fantasy and daydreams. The emotions are deeper than those found in my last album,'' Luk told Young Post. Luk's love for music began young. He took to the keyboards at seven and formed his own band six years later. ''I love pop music with a jazz sound. We are not so much a band, but my friends and I like to come together, rent a studio and 'jam' music at our leisure. I play the keyboards and the drums.'' If anyone has noticed, the voice behind the Cantonese theme song for the popular TV cartoon series Dragon Ball is Luk's. Luk has an incredibly carefree attitude towards studies and his singing. ''I believe in letting things take their natural course,'' he said, ''but I'll take any opportunities that come my way.'' Wearing his red cap from back to front, casual T-shirt, baggy jeans and sneakers, Luk looks no different from any teenager. Although he would love to continue his studies, especially in Western History, the HKCEE result is not a worry yet - he will be too busy with his filming this summer. ''I'm very excited about my first acting attempt, it is an opportunity that came out of the blue,'' he said. ''I will play an ancient scholar who falls in love with a prostitute and elopes with her.'' Drama beckons and the energetic singer is certainly venturing to prove himself. Before the end of the month, Luk will be in Malaysia and Singapore to promote his new album.
