Taku: *breathes*
Readers: Now that's suspicious
(Seriously tho, what's so suspicious about Taku?)

I mean, there's good reason to wonder about Taekyung's motivations. I'm going to repeat some of my own past comments here, but: First of all, there's the fact that he doesn't bother differentiating between being interested in someone as a model or being interested in them as a romantic partner.
Secondly, at the beginning of the webtoon Taekyung says the people he dates are like "candy"—specifically cheap, artificially-flavoured, interchangeable candy, which implies something shallow and briefly pleasurable. The author frequently mentions he tastes like candy, or shows him eating candy, especially after sex. She doesn't want us to forget that he said that.
And then, of course, there's the convo in Ch. 44, where Haesoo's being hesitant again and Taku kisses him in spite of being rejected and showing a pretty darn suspicious expression at the very end of the scene.
Is it totally possible that Taekyung's just kinda a weirdo and Haesoo's his first real crush? And that the candy stuff is a red herring, or only applies to Taku before he met Haesoo and really fell for someone? Yep. Could he just be annoyed in the latest chapter that all his progress in his relationship with Haesoo has been ruined, and that odd expression was just him plotting how to get back at Leo and make sure this doesn't happen again? Maybe! But it's not like readers are coming up with this out of nowhere.

Zhi Shu dies from his illness. Jiang Wenxu never sees him again since the day he left. After Zhi Shu dies, Wenxu starts harming himself but remembering Zhi Shu made him clean himself up. He writes a heartfelt letter to Zhi Shu and tells him (in the letter) that he will be waiting for Zhi Shu (even if he's actually never coming back). As for the doctor, he's also left heartbroken. He follows Zhi Shu's request to be cremated and spreads his ashes in Lake Baikal in Russia. It was implied he'll never love again.
