Cyno is like a walnut. He's all hard on the outside, but he's soft in the inside. He’s like a burnt marshmallow- in which once you get through the hard, burnt outside layer you arrive to the soft gooey centre. And it IS worth traversing the hard layer because once you reach soft Cyno he will be the sweetest thing you’ll have ever known.

Because once Cyno gets to know you, once Cyno starts to connect with you, once he starts to care for you and realise he might-possibly- perhaps - maybe love you he is prepared to do anything for you to make you happy and safe.

If you're anxious, he’ll hold your hand to make sure he’s there for you, if you feel cold he won't hesitate to hand over anything he has to make you feel warmer (although I doubt it will be much- I mean my man’s walking around barefoot and practically shirtless) and he’ll piggy back you if you're tired from walking. (no matter how heavy you are) if you can't sleep, he’ll stay beside you and help you- he might try relax you with his voice, or tell you stories to help you sleep, or cuddle next to you until he feels like your breathing normalises as you drift into your dreams.

if you're feeling self- conscious he’ll compliment you- because to him you're already beautiful. He might supply you with gifts- though usually they're really hand made and thought out, he’ll make your favourite food, comfort you when you’re not well....

If you feel uncomfortable in your clothing- he WILL learn how to knit to make the clothes for you, he’ll remember what you love, cook the food you enjoy most- and like @cynotical said he’ll put his hand on the corner of tables so you don't get hurt. Cyno will gladly give you the whole bed if you're one to take up space or need to roll around (for your comfort and for his own) and as @perpetualcynicism said he’ll chop the onions for you so you don't have to

Because even if Cyno might give off a “I don't care about you, I'm cold, harsh, be scared of me” kind of vibe- because yes you were scared of him when you first met him- from his harsh and quite intimidating wall, that wall broke as soon as he met and saw you.
