Happy course (recommended)
Goddess of the snipe (highly recommended, absolutely beautiful, absolutely cured, with a good ending)
S egg
The magic of zero (it was awesome at first)
Cross and vampire (very cute)
Divine comedy (recommended)
Ghosts (now only in episode 7, but the follow-up plot should be good)
Hayate the combat butler (needless to say, the first and second seasons, the harem part is mainly concentrated in the second season, but it didn't come out until the second season and the eighth episode)
Tomorrow and one
Let's take a look at these for now. These are all classics I have seen. The people's design, sound quality and story are all very good. Of course, the ending is definitely happy. After reading it, people feel happy and have an impulse to watch the sequel. Take a good look.
