As i understood he s not the reincarnation of that seme, he s a grandson, so maybe it s about genes or the way he was raised by his grandpa. But hosik is a reincarnation , cause he has some memories of his past life. But i m not sure anyway))
Yeah it really depends on the reader's point of view. But what I know is, they are indeed connected with the past.
Omg y diddnt i think of thiss, it wass so obvi that seungyeon is maybe a descendant of the past seme WOWOWOW
Finalllyyyy someone who knows why Sungyeon was possessiveeee, it was because he was afraid of losing Hosik again
Now it makes sense why Seungyeon was so overprotective with Hosik bc of their past life. Although, he may not remember it, his feelings was the same especially when he failed to protect Hosik in the past. Its 1 am now and (╯°Д °)╯╧╧
