[5278] PROJECT's third single, [After Rain]. "MuKuRo" has original lyric and rap skills and high songwriting ability, and "OSAMI", who is also a member of Tokyo Young Vision, uses his high songwriting ability to incorporate a wide range of songs from intense sounds to emotional songs. A previously unrealized collaboration between the two has been realized through producer "NAOtheLAIZA". This song is a high-quality work that seriously shows off the power of each songwriting. The song is full of originality, with a pleasant melody and somewhat sad yet powerful lyrics that evoke the emotional emotions of the Japanese people. The beat is based on the UK DRILL by "NAOtheLAIZA" and has a pleasant sound.
