 If you liked Ijiranaide, Nagatoro-san |  ...then you might like Ookiku Nattara Kekkon suru! |
This is a love story of a man who wants to pursue Heroine. It's a little weird but I really recommend it for you. Nagatoro is a story of bullying so this is a story of men's struggles for Heroine. It has something in common with the MC which I think is looked down upon.
