I'm sorry for replying so many times but Mangago doesn't let users delete their replies or edit them.
In the author's note, they said that Dayeol usually bottoms, but Taehyun would bottom if Dayeol wanted him to. But ultimately, their sexual dynamic is left open-ended so fans can interpret whatever they personally want since it doesn't really matter
Due to ur settings in mangago i cant directly reply to you so i hope somehow u see tis
Regarding ur response-
Not sure tbh, when reading it, it just gave me that vibe. I mean if its how u said den it works out but idk. I mentioned "I think" but I'm not 100% sure since there has been no such s*** scenes ygm. And their dynamic just looks like a switch relationship where both of em would be top n bottom n technically would fit the story n them

The ending could have been extended cz I think there is still a barrier in the relationship and that's Taehyun opening up to his feelings. He is keeping stuff bottled like how he dislikes tis or rhat, gets jealous etc whoch is a good ting but it's best to tell his partner. By the story I think Tae will be bottom, tho switch would be nice altho from looks of it Tae defo bottom. I like the story bur like I said Tae gotta open up slowly n let him know he gets jealous, or hates tis that, dislikes tis that, likes tis that, or etc
