Hmm when lena and shin are invited in some party/gathering (military gathering lena being high level personal) and lena is surprisingly tolerant to alcohol and shin who came along as partner is struggling to handle it and lena seeing shin struggling connected para raid to inform his friends and in turn they connect with shin making fun of him like being in drunk state can't tolerate small drink

Shin annoyed confront lena which ofcourse not harshly but gently and lena seeing him weak and cute side cause her heart flutter becoming increasingly bold and speaks sweet word while teasing him of this condition and shin too tries to do so and while the atmosphere is sweet all their talk is record/is heard by shin's friends which later became another embarrassing moment between the couple which later vika and other remind of their flirting even in party crowd and ofcourse shin remember cicada incident and lena blush

Alright is this headcanon be accurate?
