Smokescreen is sick one day you had to take care of him. When it was time for you to go, smokescreen cried out

Smokescreen: y/n, don't go!
You: I'm sorry, smokescreen, but I should've been home an hour ago. I promise I'll be back tomorrow to check on you. Goodnight.
Smokescreen: no! Come back! I don't wanna be- *you close the doors sadly he gasps in tears*  ...alone. *he plops on his berth* I needed you, y/n! Please!!!!

Smokescreen cried all night and all the next day. Later on that afternoon, you returned back to base to check on smokescreen. Smokescreen turns into his human form and hugged you tight while weeping.

Smokescreen: I'm so glad you came, y/n! *tears flood his face* I can't stand being alone! I needed you so badly! I... I... I love you!
You: *cups Smokescreen's face* I love you too

Feeling your soft touch on his teary face, smokescreen starts screaming and crying as he hugs you tight, refusing to let you go.
