My theory about Yoshida

SimonGhostRiley said:
I like to think that Yoshida is Ryuuji from Toradora and that the main reason he's into older girls and not little ones is because he had a bad breakup with Taiga, or that she died and he has trauma he's not ready to face so instead he's only romantically interested in older women with bigger breasts (the opposite of Taiga's size). Ryuuji leaves town and goes to Tokyo changes his name, and lives out his days when he meets Sayu on the street, where he has a quick flashback of Taiga. He takes her in because he wants to be reminded of his youth days, the days back in high school with the girl he loved. He helps Sayu out so he can finally feel like someone needs him again like Taiga did. He wants to feel something, anything. His trauma left him broken. A broken Ryuuji, reminiscent of the days where he felt most alive.

I thought of this all because of Yoshida's eyes. His. Eyes.

I hope in season 2 they delve more deeply into Yoshida's (Ryuuji's) past and really bring out his trauma that he's clearly trying to run away from just like Sayu was running away from hers.
