I found my headcanons about the male characters' love languages! Usually I don’t really do these (I prefer canon facts over headcanons), but these are probably my favourite.
I would love to hear any other headcanons about this, too! Feel free to share your opinion in the comments, if you want to add / don’t agree with mine!
Quality time, Acts of Service, Physical Touch, Words of Affirmation, Gifts.
Giving:
💛 | Tsukasa — GIFTS as his bestest love language (he likes to exaggerate with them, but it always looks very genuine and not at all out of place, his love is just that big), acts of service;
🧡 | Akito — physical touch (would probably be extra clingy (when alone) because “you’re mine”), acts of service;
💙 | Toya — quality time, words of affirmation;
💜 | Rui — acts of service, gifts (handmade).
Receiving:
💛 | Tsukasa — physical touch (hugs or kisses on the cheek, holding his arm so he’d feel like a gentleman), words of affirmation (simple “I love you”, but it’s very important for him to hear);
🧡 | Akito — words of affirmation (“you’re worthy” and etc., based needs for Akito), physical touch (would get awkward at the innocent gestures but likes when someone leans on him so he could feel like he can protect that person and be a safe place for them);
💙 | Toya — physical touch (that makes him feel cherished and secure, like kissing / caressing his hands / face, or holding him; very gentle and quiet type of love), words of affirmation (compliments about his personality (mostly) and appearance);
💜 Rui — gifts (would keep and cherish them until he dies), physical touch (holding hands, caressing his hair while cuddling; he likes feeling that his person is nearby and / or cares for him enough to touch him).
