Just hearing Kikuchi's whispery vocals and the melody brings me back to my U of T days and videotapes of "The Best 10". The single was released in May 1985, and hit the top spot (her 2nd time at the top after "Sotsugyo"[already profiled]) on Oricon and later became the 22nd-ranking song of the year. It is on the soundtrack album and most likely also inhabits any BEST compilation for Kikuchi. The song was created by lyricist Yasushi Akimoto（秋元康） and composer Tetsuji Hayashi（林哲司）.
In a nifty piece of coincidence, at about the same time as the release of "BOY no Tehma", fellow aidoru Seiko Matsuda（松田聖子）also released her single "Boy no Kisetsu"(ボイの季節....Boys' Season). The two songs occupied the No. 1 and No. 2 spots on Oricon, according to J-Wiki, although it's not said which one occupied which position.
