manga/manhwa where the lead (not mc) has a lot of mood swings :0? Like the lead from candy...

how can a lead not be an main character? Like a side character? ;-;
anyway, assorted wildness has a uke who tends to have a lot of mood swings, and he also makes really quick decisions. I'm not sure what you're asking really, but id recommend reading it.

Not sure what you mean but http://www.mangago.zone/read-manga/on_my_own_1/ both seme and uke have mood swings between both sad and happy
