Kimi no Sumire: Your Spring Flower

Sumire Kimino has transferred to a new school, and is eager to jump into his new surroundings. What stands out the most to him are rumors about Suguru Tojo, an upperclassman who is known as the most beautiful boy in school. Sumire expects that such a legendary student would want nothing to do with him, but through coincidence, the two of them end up getting closer, spending time together and delving into past trauma.
