Ygret

just read the 1° season (up to ch.49)…

it’s very slow. the MC is basically a baby up until ch.30ish.
There’s basically no action, but it’s heavily focused on emotions: sadness, abandonement complex, regret, not using his powers.

MC is not “weak”, but he is… the embodiment of purity and “good”, even to those undeserving it. He is always unnaturally calm, happy or sad. There is not a single time where he gets a masculine urge to smirk, get angry, provoke, prevail, not even pity or anything: it’s just calm, happy or sad (mostly sad).
i don’t know if there’s a word to describe such a strange and annoying behaviour, i would say the most fitting (albeit not completely) is: coward.

this is basically a shoujo with a male protagonist. You can either trust me or waste your time reading this to get to the same conclusion. Make a smart decision: 1 star.
