I feel the same, didn't feel much either but felt more from that kissing chapter. these chapters were building up to something which is to get answers and resolve the situation, they didn't solve anything. It's like nothing happened and brushed it off and all of a sudden we got this chapter, it feels like it wasn't earned if that makes sense lol. I'm very disappointed by this chapter as I wanted things to clear up and hear what happened, especially He Tian has a lot to explain.
I 100% agree with everything you wrote! It really didn't feel earned, that's a good point.
Okay, we can be 80% sure they actually slept with each other which is insane considering how long we've waited. Yet I don't feel much? Unlike their first real kiss (somewhere between chapter 410-412) this time there was no romantic built up - just an unsolved fight, then like two months no updates and then BAM fucking. But also with veery subtile hints and so quick... I'm not complaining though, just analyzing, I guess.
