Unless, of course, if Senzaki died. Im worried with his "This will be my final disappearance". The window scene at the last part had me troubled as well huhu. Also, I was thinking of them doing double suicide if Yoichiro did come (well, maybe not xD) prolly because of the line I mentioned.
Honestlyyyyy, I just feel like sobbing. What do you think happened at the window scene ヽ(;へ;)ノ

Omg.. There might be a chance of Senzaki doing that. :(
Senzaki mentioned, "I will keep bugging you while you try to be happy. No matter how far you run, I will track you down and bring misery upon you.."

These lines may be interpreted in different ways:
a. If Senzaki's dead, Yoichiro will be definitely sad and be "bugged" for the rest of his life (maybe). He might not be able to forget and move on after all.
(Which may be a support to your theory. (●'◡'●)ノ )
b. If Senzaki's alive, he might do crazy things like hurting his family (eg. brother) and interfering with his academics and future career.. or kill him? I really don't know. Haha. With him being crazy, he'll do unimaginable stuffs.
Your theory makes me want to cry, but it's nice. :) In the window scene, I believe that Senzaki's alive. Yoichiro's still waiting for him "to put an end to his breathing".

Hi lol super late with replying but here I am.
Its so sad that when I was reading the recent chapter, I thought "OMG they gonna die together because no place herwe is not boring for Senzaki"
I do think about option B, but I dont think Senzaki will be doing any of those. Gut feeling maybe? Or coz he said that Yoichiro will be the one choosing this time. Meet him for the final disappearance or not, either way, Senzaki will go byebye.
I read an interesting comment about the window scene from someone, and that makes sense too. She said that Senzaki is haunting Yoichiro, which means that hes dead already. Thats how he'll bug Yoi-chan and make sure to follow him forever. Now if sensei continue their story and Senzaki is indeed dead, this will have a very psychological plot. Unless something supernatural happens, it'll be Yoi-chan's mind playing games on him.
Im such a pesimistic prick huhu

NIIIICE! :) If ever Senzaki's dead, I am looking forward to how will sensei portray the bugging acts within Yoichiro's mind.
I know that this manga's genre is psychological, but I'm amaze how this manga can be "more psychological" =))) lol (I don't know how to explain anymore haha)
I am becoming more and more excited for the updates of this couple. I think there would be 5-7 chapters before the couple gets their own story again :(
Anyways, let's just wait patiently. :)
(Btw, thank you for your response. I reaaally enjoyed reading your responses. (▰˘◡˘▰)
Thank you for not forgiving Yoichiro... It means, they'll have a part 2! <3
Lol, but seriously speaking... I do really love this couple. It is undeniable that they love each other so much. I love Senzaki's loyalty and persistence (but not quite his sadistic side)
But, I would also like to commend Yoichiro for not leaving his family. Even though he hates his father in some ways, he still considers following his legacy. He also considers his mother who only wants to give the best in life for her son.
I do believe that sooner or later, their love will lead them back to each other. K. :D
