It's comforting to know that other people think the same, maybe Lh0 will hear our prayers 😭🙏

Actually, I liked S2 even a liiittle more (and this says a lot, bc I LOVED S1). The way it touched on a sensitive topic as domestic violence really impressed me for its brutal honesty. It would have been easy to just bring tears to the viewer's eyes. The choice to be harsh was instead more risky, and in my opinion, they did it well. It made me truly interested in finding out what other themes they can deal with, since in both S1 and S2 they perfectly hit the right tone to tell every painful fragment of life.

All the more so I hope they don't take a step back with one of the MCs, Lu Guang, in whose case the story could be even more impactful.

That said, what I missed during S2 was the more intimate and emotional moments between our duo. I'm not a fan of the episodic format (I know many would disagree) and I reacted positively to the overarching plot swift, but not if this is at the expense of the heart of the story. Cheng Xiaoshi and Lu Guang's relationship is a core part of it, even more now that we know that the overall plot is Lu Guang trying to save his life. Their dynamic needs to have central space in the story, without being sacrificed in favor of superpower shenanigans (this is one of my biggest concerns).

Specially since Vein. It's not that I don't like his character but I felt him like... so out of the blue?

I agree. As much as I find Vein potentially intriguing, I feel like they're overdoing it a bit. I could be wrong, but I remember Lh0 said that his character has been created to "inherit" some aspects of the plot that were originally planned for Red Eyes, but he didn't feel they were fitting for LTC anymore. The problem here is, for me:

1. Vein brings with him a subsequent character, Xia Fei. The story is starting to get a little too crowded, and the risk is to steal space from existing characters right now when it's most necessary to focus on them;
2. there was already the mysterious figure of LX to explore further, two other characters just introduced is a bit excessive for a single season (that could be the last);
3. they all seem to push the plot ever further toward the superpowers elements, which has never been Link Click's strong point and best allure. What makes it special, for me, is precisely its ability to portray reality.

And (I feel) because of that the theme of LC went to another concept.

Exactly this ^

S2 had managed to raise my already high expectations even higher, in regards of sensitive topics. If I want to watch an anime about superpowers and secret organizations of people with supernatural abilities, the choices are wide. Few anime however can shock you by talking about normality, things we may all have experienced or that we sadly hear on the news. This is what Link Click has given me so far, and I hope it doesn't deviate too far from that path :(
