I think Heasoo and Joowon were a great couple they had the opportunity to be happy but their love was so imature. Now they understand each other, are mature, (this break up was needed) but Taku is a better choice for Heasoo. With Taku Heasoo understand what love means, love is not sleeping with other guys and in evening you turn back to your husband (Joowon), love is not addicton, love is something that makes you feel good and free. Love doesnt mean to hide secrets from each other, loves means to be true with your self and your partner. Taku didn't understand this also, he hurted his boyfriend because he didn't show feelings. When he found Heasoo, he felt in love, and for the first time in his life he doesn't want to lose someone, he is working hard that Heasoo to not leave him.
Joowon was selfish in the beginning, but now he is mature now he understands how much worth had Heasoo for him, and he understands is late but at least he got a leasson from all of this. Heasoo is confused right now but i think Taku was the one who awaked him from that let say "addicton relationship" he had with Joowon. When he was with Joowon he slept also with other guys, but with Taku he even refuse to sleep with Joowon. Taku made him to understand feelings more deep. I really, i really want them to be happy, the three of them and for my opinion this is the right choice. Someone should take a leasson in the end of this, to preciate the value of things.
