"- With "Skinship", you can touch your comrades' faces (regardless of gender) and improve the bond between you and them. These improved bonds affect units stats when engaged in battle within "Attack Stance" and "Guard Stance". This can also allow your bonded unit to receive a "Surge" in stats, which is a temporary stat boost for the next battle. Be warned, that skinship isn't as easy as it may seem, since certain characters prefer to be touched in certain ways or places. Just as you can be successful, you can also fail in building a bond with skinship."
