aaa it's close but thank you!! Will definitely try reading it! I finally found the name of the manga which is Taiyou no Ie and I completely got the wrong description, whoops! ┗( T﹏T )┛
There's kinda bits of romance, a female student with long black hair who i think has family problems, and a male office worker or teacher?
