similarities:
both series' male protagonists are a couple with the female protagonists and have known each other since childhood and are also wearing glasses
differences:
tetsuro tanaka (Koi koi 7) is immediately welcomed by the heroines and protects him while keitaro urashima (love hina) recieved torture on his first encounter with the heroines (except for shinobu who debuted in episode 2 and motoko who appeared in episode 3)
also, sakuya kamatsuri and kaolla su seems to be both experts in weapons specially when the latter used a bazooka to chase off a disguised keitaro (they'd even make a perfect team)
