I LOVE THEM SO MUCH UGH THE WAY THEY COMMUNICATE IS SO MUCH BETTER THAN 90% OF COUPLES! I love how they try to understand and accomodate each other without coddling the other too much, i love to see how they grow individually and with each other! Especially Fujinaga's job is so interesting to me because he can apply what he has learnt there in many aspects of his relationship ヾ(☆▽☆)
Taeyoung might have a strong fear of abandonment. I don't think his actions were complete possessiveness but a mixture of anxiety too. It's evident in the way Taeyoung questions why didn't Jinwoo come to him first and in the way Taeyoung obsessively marks him. Might also be the reason he only pursues casual relationships to avoid the intimacy that comes with serious ones. It could be due to his childhood where his mother might have "given" Taeyoung to his father to stay with him and essentially abandoned him.











YES THEY FINALLY GONNA CRACK (๑•ㅂ•)و✧
