>>3 Series that gives you depression means that it leaves a lasting impression, which I suppose translates into 'good', according to my dictionary at least.
Try Kaguya-sama's Love is War I think, if you hadn't tried that. Top tier comedy-romance series, sprinkled with some heartwarming moments every now and then. Third season will be airing this april, a chance to catch up on the hype train. The climax of the whole confession shenanigans will peak on this season, its the most anticipated arc in the manga that will finally get an adaptation.
The ongoing My Dress Up Darling is pretty good as well, someone should make a thread about it.
