FATHER AND TEACHER. HAS A SEQUEL: YOAKE NI FURU.
Hoshino was dazzled by his senpai, Akihino, when they formed the astronomy club together in high school, especially with his dreams of becoming a pilot. What he didn't know is that those dreams had only become an opportunity for Akihino because he was dazzled. After an eleven year separation, Hoshino is astonished to be reunited with Akihino, who has not been able to fulfill his dreams. Indeed, it seems that he is the single parent of Hoshino's biggest problem student and there is a sad mystery behind this, but Akihino does not want Hoshino to come any closer. A bittersweet story about adulthood and sacrifices, which becomes much sweeter when barriers are slowly worked through, although it's sometimes frustrating to watch.
Okay i think i understand why the sempai say all those hurting words to him (because he tried to push sensei away, just like when theyre in high school), but pls at least give some redeeming point to the senpai? Make him apologize to hoshino or just make him saying some warm words or just anything? It made me so sad to see how strong hoshino's feelings and struggling but the author choose not to display senpai's emotion. Made me hate the senpai a little (a lot)
