Wagamama Ouji to Naisho no,

The usual days, the usual after school. Suddenly, a beautiful prince with jet-black eyes and brown skin appears in Haruto's ordinary life! And what's more, the prince is home-staying at Haruto's house.
The prince kisses him in front of everyone, honey traps him with sexy clothes, attacks him in his sleep, and tries to seduce him in every possible way?!
